How to convert timezone in number to UTC?

I have some random dates with different timezones, they are in formats like this "07 Mar 2022 13:52:00 -0300", or they could be like this: "07 Mar 2022 11:12:00 -0700". I don't know which timezone exactly they will be coming from. How can I convert all of them to UTC time "0000Z"?

You can use standard module datetime for this.

Function strptime() (string parsing time) can convert string to object datetime using matching pattern. For your examples works pattern '%d %b %Y %H:%M:%S %z'

Next you can use .astimezone(datetime.timezone.utc) to convert to UTC.

And later you can format string with strftime() (string formatting time) using again pattern '%d %b %Y %H:%M:%S %z' (or you can skip %z)

Minimal working code:

import datetime

data = [
    "07 Mar 2022 13:52:00 -0300",
    "07 Mar 2022 11:12:00 -0700",
]

for item in data:
    print('before str:', item)

    dt = datetime.datetime.strptime(item, '%d %b %Y %H:%M:%S %z')
    print('before dt :', dt)

    dt = dt.astimezone(datetime.timezone.utc)
    print('after  dt :', dt)

    print('after  str:', dt.strftime('%d %b %Y %H:%M:%S %z'))

    print('---')

Result:

before str: 07 Mar 2022 13:52:00 -0300
before dt : 2022-03-07 13:52:00-03:00
after  dt : 2022-03-07 16:52:00+00:00
after  str: 07 Mar 2022 16:52:00 +0000
---
before str: 07 Mar 2022 11:12:00 -0700
before dt : 2022-03-07 11:12:00-07:00
after  dt : 2022-03-07 18:12:00+00:00
after  str: 07 Mar 2022 18:12:00 +0000
---

I would suggest to import datetime, then use the following method to convert your time stamps into datetime objects (where str is the time stamp as a string): time_stamp = datetime.strptime(str, "%d %b %Y") (where the parameter after str gives information on the formatting; for details see here: https://www.programiz.com/python-programming/datetime/strptime).

After that, you can use datetime.astimezone() to convert this into another time zone.
