It seems that RustPython supports datetime().astimezone() while the implementation of this function is broken and attribute 'tm_gmtoff' is missing. See the following example.

Example.py

from datetime import datetime
datetime(3001, 1, 19, 7, 59, 59, 999999).astimezone()

Output on RustPython:

Traceback (most recent call last):
  File "/home/xxm/Desktop/RustPython/example.py", line 199, in <module>
    datetime(3001, 1, 19, 7, 59, 59, 999999).astimezone() 
  File "/home/xxm/.cargo/git/checkouts/rustpython-f8ef4d934ac33cd8/59df92d/pylib/Lib/datetime.py", line 1862, in astimezone
    tz = self._local_timezone()
  File "/home/xxm/.cargo/git/checkouts/rustpython-f8ef4d934ac33cd8/59df92d/pylib/Lib/datetime.py", line 1856, in _local_timezone
    gmtoff = localtm.tm_gmtoff
AttributeError: 'struct_time' object has no attribute 'tm_gmtoff'

Behavior on CPython: works normally

Environment:
RustPython: v0.2.0 (https://github.com/RustPython/RustPython#59df92d7)
CPython: 3.9.0
Ubuntu 18.04

both tm_gmtoff and tm_zone are missing from the struct_time struct:

RustPython/vm/src/stdlib/time.rs

Lines 318 to 328 in 59df92d

struct PyStructTime {
tm_year: PyObjectRef,
tm_mon 90BC : PyObjectRef,
tm_mday: PyObjectRef,
tm_hour: PyObjectRef,
tm_min: PyObjectRef,
tm_sec: PyObjectRef,
tm_wday: PyObjectRef,
tm_yday: PyObjectRef,
tm_isdst: PyObjectRef,
}

reference, Python docs on these: https://docs.python.org/3/library/time.html#time.struct_time

Might be easy to add them.
