== Overview ==
This namespace contains functions that deal with date and time.

Note that most of the functions have been implemented by Phil Last (http://aplwiki.com/PhilLast) - unless stated otherwise - and generously granted to the APLTree project.

This class does not need .NET.

== Examples ==

The following table gives examples for all functions. The table is ordered by categories.

Note that not all syntactically possible features are demonstrated by these examples. For details execute:

      ]ADOC_Browse #.DateAndTime
}}}

(What is [[ADOC]]?) (What is the [[UserCommands/Adoc|ADOC user command]]?)
