This plugin extends Take Command’s date-handling functions to support new date formats, including ISO 8601 week-date and ordinal-date formats, MS-DOS and ANSI day numbers, and offsets from today’s date; a larger (8,399-year), consistently enforced date range; and more consistent validity checking of input dates. Most of Take Command’s internal date-handling functions have been re-implemented to support this new functionality, and many new functions have been added to make date-handling tasks easier. A few ISO 8601-related internal variables have been re-implemented in order to make them available in older versions of 4NT and Take Command. This plugin also features a popup date picker for use in interactive batch files. The plugin also includes one new command which displays a simple calendar, and another to enforce the use of four-digit years.
In addition, there are several new functions to handle basic time-related math such as adding or subtracting times from a specified start time, reporting the difference between two times, converting local times to and from UTC time, and converting hour/minute/second times to and from decimal days.
