DateTime¶
Usage
use DateTime;
Support for representing dates, times, combined dates and times and timedeltas. This module is modeled heavily off of the python module 'datetime'.
For more detailed descriptions of this functionality, please see the python docs:
https://docs.python.org/2.7/library/datetime.html
Operators are supported for adding, subtracting, and comparing dates, times, datetimes and timedeltas.
Operators are also supported for multiplying and dividing timedeltas.
