ISO 8601 duration parser

timedelta-iso8601

timedelta-iso8601 is a pure-Python implementation of ISO 8601 duration parsing that does not rely on regular expressions.

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

Usage

>>> from timedelta import timedelta
>>> from datetime import datetime
>>>
>>> millenium = datetime(year=2000, month=1, day=1)
>>> now = datetime.utcnow()
>>>
>>> td = timedelta(seconds=(now - millenium).total_seconds())
>>> td.isoformat()
'P8310DT16H21M3S'
>>>
>>> millenium + timedelta.fromisoformat('P8310DT16H21M3S')
datetime.datetime(2022, 10, 2, 16, 21, 3)
