Use datetime with different timezones (discord.py) - python

So I'm trying to code a bot and part of it requires the "Last Seen" variable for when the user last logged onto the server (minecraft). I have an API that is set up to to detect when the user joins and post it in discord, but the issue is that when i translate the variable into datetime, it invariably gives me the time in UTC. Is there a way to translate the code into EST or another timezone?
The Code:
embed.add_field(name = "**Currently Playing**" , value = "Offline" , inline = True)
embed.add_field(name = "**Last Seen**" , value = datetime.datetime.fromtimestamp(int(lastseen)).strftime('%Y-%m-%d at %H:%M %z %Z') , inline = True)

You could use pytz for your problem.
import pytz
timezone = pytz.timezone('<timezone>') # Setting timezone
utc_now = pytz.utc.localize(datetime.datetime.utcnow()) # UTC
tz_now = utc_now.astimezone(timezone) # Converting to specified timezone
print(tz_now)

i'm trying to convert my local windows system timezones to uk timezone using python

i'm trying to convert whatever the user select time timezone it should convert into uk timezone. I've found a package in python called "pytz" but the list of timezones are different from my windows local system timezones. I've searched for micorsoft default system timezones and trying to convert them in uk timezones
please click the below link for microsoft default system timezone details.
https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/default-time-zones?view=windows-11
for example instead passing 'Asia/Kolkata' to my "get_uk_time" function i'm trying to pass windows local system timezone as "Chennai, Kolkata, Mumbai, New Delhi" or India Standard Time or IN. similar way for other timezones which are available in the microsoft link above
i've tried below approch but unable to find how to convert above local windows system timezones.
from datetime import datetime
from pytz import timezone
def get_uk_time(time_zone):
try:
country_tz = timezone(time_zone)
format = "%Y, %m, %d, %H, %M, %S"
time_now = datetime.now(timezone(time_zone))
format_time = time_now.strftime(format)
london_tz = timezone('Europe/London')
local_time = country_tz.localize(datetime.strptime(format_time, format))
convert_to_london_time = local_time.astimezone(london_tz)
uk_time = convert_to_london_time.strftime('%H:%M')
return uk_time
except:
print('unable to find the timezone')
my_json = {'timezone': 'Asia/Kolkata'}
time_zone = my_json['timezone']
time_in_london = get_uk_time(time_zone)
print(time_in_london)
please help.

How do I convert an API UTC time to local time (+13:00)

I am trying to convert a datetime from an API that stores datetime values as UTC. I need to convert the datetime to my local time 'Pacific/Auckland'
The API I am using is Sunrise-Sunset https://sunrise-sunset.org/api
The specific location I am requesting is Christchurch, New Zealand https://sunrise-sunset.org/search?location=christchurch
import requests
api_url = 'https://api.sunrise-sunset.org/json?lat=-43.525650&lng=172.639847&formatted=0'
response = requests.get(api_url)
if response.status_code == 200:
sunset_today = response.json()['results']['sunset']
print(sunset_today) # outputs '2021-09-26T06:31:41+00:00'
I have searched StackOverflow and Google extensively, but cannot seem to find a solution that fits my needs.
The question I am asking is
How can I convert the UTC value to my local datetime ('Pacific/Auckland')?
FYI, I don't want to add bloat to the application, but from previous (unsuccessful) attempts at solving this problem I have already installed the tzlocal and pytz packages.
I am writing my application in Django 3.2.7 and have adjusted my settings.py TIME_ZONE = 'Pacific/Auckland'
Edit
When trying to convert the string to a datetime I get the following error.
time data '2021-09-26T06:31:41+00:00' does not match format '%Y-%m-%dT%H:%M:%S %Z'
sunset_today = response.json()['results']['sunset']
format = '%Y-%m-%dT%H:%M:%S %Z'
parsed_date = datetime.strptime(sunset_today, format)
print(parsed_date)
# ERROR: time data '2021-09-26T06:31:41+00:00' does not match format '%Y-%m-%dT%H:%M:%S %Z'*
To convert timezone aware string to python datetime easier to use fromisoformat, since you are getting ISO formatted string from API anyway:
import datetime
sunset_today = response.json()['results']['sunset']
parsed_date = datetime.datetime.fromisoformat(sunset_today)
# 2021-09-26 06:31:41+00:00
I solved the problem using the dateutil and pytz library
import requests
import pytz
from dateutil import parser
api_url = 'https://api.sunrise-sunset.org/json?lat=-43.525650&lng=172.639847&formatted=0'
response = requests.get(api_url)
nz_zone = pytz.timezone('Pacific/Auckland')
if response.status_code == 200:
sunset_today = response.json()['results']['sunset']
converted_date = parser.parse(sunset_today).astimezone(nz_zone)
print(converted_date) # outputs 2021-09-26 19:31:41+13:00

Timezone getting removed in python flask

After a user logs in, I am setting a session variable to the time with utc.. but the timezone is getting stripped.
import datetime
from pytz import timezone
utc = timezone('utc')
session['login_time'] = datetime.datetime.now(utc)
When I print after the assignment the timezone is there 2021-06-11 23:56:00.161971+00:00. And a decorator function gets called. When I print session['login_time'] the timezone is removed. 2021-06-11 23:56:00
For me, I will use .strftime to help format the datetime and %Z is to show the timezone.
You can see the strftime document to help you format the time. I will use this code to replace your original one:
session['login_time'] = datetime.datetime.now(utc).strftime('"%Y-%m-%d %H:%M:%S%Z"')
login_time = datetime.datetime.strptime(session['login_time'],"%Y-%m-%d %H:%M:%S%Z" )
utct = utc.localize(login_time)
print(utct)
print(type(utct))
And here is the output:
2021-06-12 01:00:23+00:00
<class 'datetime.datetime'>
I had to re-add the timezone('utc') when i needed to use the time in another function.
def diff_min(t):
utc = timezone('utc')
t = utc.localize(t)

Convert UTC time into local time using python

i want to convert UTC time into user's browser time.
i have tried a loat but its display me system time only.
working with django application. can anybudy help me out.
import pytz
from tzlocal import get_localzone
def utc_to_local(utc_dt):#utc_dt that is UTC time
local_tz = get_localzone()
print local_tz #that is display system timezone inplace of USER's timezone
I have tried with below code.
import time
from datetime import datetime
from dateutil import tz
utc = datetime.strptime(str(utc_dt)[:19], '%Y-%m-%d %H:%M:%S')
return time.mktime(utc_dt.timetuple()) * 1000
convert utc time into second and then using javascript need to make it localtime. but conversion value not accurate and its display me wrong date.
Javascript code.
//1449206930000 #Seconds when above code run
//1449226703.79 #that is correct >> time.time() in python = 1449226703.79
#below code give perfact output
var date = new Date(parseInt(1449226703.79, 10) * 1000);
console.log(date);
#below code not working
var date = new Date(parseInt(1449206930000, 10) * 1000);
console.log(date);

You need to find the users timezone first, to convert time in there local timezone.
There are two ways to do it.
1) Pass simply UNIX-timestamp then use a Javascript to convert it in human readable time on the browser momentjs can help you with that.
function human_time(unixtime, tz) {
var t=moment.unix(unixtime);
return t.tz(tz).format('DD/MM/YY HH:mm:ss');
}
2) Use IP address or HTTP headers to detect the user location and then use pytz to convert your time in users system timezone instead of your own django/server timezone.
def get_user_timezone(request):
return request.visitor.location.timezone
def human_time(dt, tz="Asia/Kolkata"):
try:
tz = pytz.timezone(tz)
except:
tz = pytz.timezone("Asia/Kolkata")
dt = dt.astimezone(tz)
return dt.strftime(r'%d/%m/%Y %H:%M:%S %Z')
def view_get_local_time(request):
tz = get_user_timezone(request) #detect user timezone, base on IP
text = human_time(timezone.now(), tz) #convert server-time to detected timezone
return HttpResponse(text)
Note: First method is the most preferable method.
import time, calendar
import datetime
utc = datetime.datetime.strptime(str(timezone_rt)[:19], '%Y-%m-%d %H:%M:%S')
return time.mktime(time.localtime(calendar.timegm(utc.timetuple()))) #convert utc time into second that correct output like function time.time()
Thanks for help.

Using python-twitter library, how to set timezone?

I'm trying to list out tweets with their time-stamps. I have this...
#!/usr/bin/python
import twitter
api = twitter.Api()
statuses = api.GetUserTimeline('ttytter')
for s in statuses:
print s.created_at + " " + s.text
Which prints out...
Sat Oct 20 04:56:47 +0000 2012 #uriel1998 W/r/t DMs, they appear just fine in 2.0.4 and 2.1 beta here, near as I can tell.
Which is pretty much what I'm after, but for the time, which seems to be in the wrong timezone. https://twitter.com/ttytter/status/259518502069760000
Is there a way I can change this within the python-twitter library? I was looking at GetTimeZone() and SetTimeZone(), but I haven't been able to figure out how they work.
Also looking at how to shift a datetime object by 12 hours in python but not sure if I need to go there.
Thanks for any help!
python-twitter returns the status timestamps as a string and as the number of seconds since the epoch. The latter is the simplest to convert to a timezone-aware datetime instance (see this answer).
Unfortunately the user's time_zone attribute is not in the standard tz database format used by pytz, so it is necessary to use the utc_offset user attribute instead (we still use the time_zone attribute to name the tzinfo created with with the UTC offset). The python-dateutil package provides a convenience type tzoffset that allows the creation of tzinfo instances from UTC offsets, which we can then use to convert the datetime from UTC to the local time zone:
import pytz
import twitter
from datetime import datetime
from dateutil.tz import tzoffset
USERNAME = 'ttytter'
api = twitter.Api()
# get a 'tzinfo' instance with the UTC offset for the user's local time
user = api.GetUser(USERNAME)
localtime_tz = tzoffset(user.time_zone, user.utc_offset)
statuses = api.GetUserTimeline(USERNAME)
for s in statuses[:1]:
# get UTC timestamp from seconds since epoch
utc_dt = datetime.utcfromtimestamp(s.created_at_in_seconds).replace(tzinfo=pytz.utc)
print('utc: {}'.format(utc_dt))
# convert to local time in the user's timezone
localtime_dt = utc_dt.astimezone(localtime_tz)
print('localtime [{}]: {}'.format(localtime_dt.tzname(), localtime_dt))
which gives the output for the first status:
utc: 2012-10-20 04:56:47+00:00
localtime [Pacific Time (US & Canada)]: 2012-10-19 20:56:47-08:00
Combining suggestions from Pedro Romano and J.F. Sebastian, I have this...
import pytz
import twitter
from datetime import datetime
USERNAME = 'ttytter'
api = twitter.Api()
user = api.GetUser(USERNAME)
pst_tz = pytz.timezone('America/Los_Angeles')
statuses = api.GetUserTimeline(USERNAME)
for s in statuses[:1]:
# get UTC timestamp from seconds since epoch
utc_dt = datetime.utcfromtimestamp(s.created_at_in_seconds).replace(tzinfo=pytz.utc)
# convert to given timezone
pst_dt = pst_tz.normalize(utc_dt.astimezone(st_tz))
print(pst_dt.strftime('%Y-%m-%d %H:%M:%S ')) + s.text
Output: 2012-10-19 21:56:47 #uriel1998 W/r/t DMs, they appear just fine in 2.0.4 and 2.1 beta here, near as I can tell. which is the correct time zone and also accounts for DST.
Thank you!
