timedelta-isoformat 0.4.3.5

Supplemental ISO8601 duration format support for datetime.timedelta

The timedelta-isoformat library provides supplemental ISO 8601 duration support to the datetime.timedelta class.

The library is pure-Python, and does not depend upon regular expressions.

Functionality is provided in a subclass of datetime.timedelta that implements additional isoformat() and fromisoformat(duration_string) methods.

Usage

>>> from timedelta_isoformat import timedelta
>>> from datetime import datetime
>>>
>>> first = datetime(year=2022, month=10, day=2)
>>> second = datetime(year=2022, month=11, day=27, hour=14)
>>>
>>> td = timedelta(seconds=(second - first).total_seconds())
>>> td.isoformat()
'P56DT14H'
>>>
>>> first + timedelta.fromisoformat('P56DT14H')
datetime.datetime(2022, 11, 27, 14, 0)
