timelib is a short wrapper around a bundled copy of PHP's internal
timelib module.

>>> import time, timelib
>>> timelib.strtodatetime('today'.encode('utf-8'))
datetime.datetime(2022, 10, 4, 0, 0)
>>> timelib.strtodatetime('next friday'.encode('utf-8'))
datetime.datetime(2022, 10, 7, 0, 0)
>>> time.ctime(timelib.strtotime("29 feb 2008 -108 years".encode('utf-8')))
