I am getting a random datetime between two datetimes with following code
start_date = datetime.datetime(2013, 1, 1, tzinfo=pytz.UTC).toordinal()
end_date = datetime.datetime.now(tz=pytz.utc).toordinal()
return datetime.date.fromordinal(random.randint(start_date, end_date))
The problem is that it is not timezone aware.
I have already tried making it timezone aware by using tzinfo=pytz.UTC
as seen in the code above but it doesn't work. I guess datetime.date.fromordinal()
makes it a naive datetime format.
If you use datetime.datetime
instead of datetime.date
in your code then .replace(tzinfo=pytz.utc)
works on the result.
To support arbitrary steps (not only 1 day
):
#!/usr/bin/env python3
import random
from datetime import datetime, timedelta, timezone
step = timedelta(days=1)
start = datetime(2013, 1, 1, tzinfo=timezone.utc)
end = datetime.now(timezone.utc)
random_date = start + random.randrange((end - start) // step + 1) * step
Note: if start
uses a timezone with a non-fixed utc offset then call tz.normalize()
at the end.
