Edit: datetime_parse.py

"""
Functions to parse datetime objects.

We're using regular expressions rather than time.strptime because:
- They provide both validation and parsing.
- They're more flexible for datetimes.
- The date/datetime/time constructors produce friendlier error messages.

Stolen from https://raw.githubusercontent.com/django/django/main/django/utils/dateparse.py at
9718fa2e8abe430c3526a9278dd976443d4ae3c6

Changed to:
* use standard python datetime types not django.utils.timezone
* raise ValueError when regex doesn't match rather than returning None
* support parsing unix timestamps for dates and datetimes
