time.mktime returns unexpected results

[azmeuk]

The time.mktime function takes a local time argument and returns a timestamp, but it seems the system timezone is used over the tz_offset value.

# dt.py

import freezegun, datetime, time
with freezegun.freeze_time("1970-01-01 00:00:00"):
    timetuple = datetime.datetime.now().timetuple()
    print(timetuple)

    mktime = time.mktime(timetuple)
    print(mktime)

$ env TZ=UTC-1 python dt.py
time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=-1)
-3600.0

The expected value of time.mktime is 0.
