=====

A time expressions library implementing a mini-language for manipulating
|

datetimes.
|
||||
|
||||
Much like regular expressions provide a mini-language for performing certain
|
||||
operation on strings, Timex's time expressions provide a convenient way of
|
||||
expressing datetime and date-range operations. These expressions are strings,
|
||||
and can be safely read from a config file or user input.
