|
|
* - 1.1 added support for +/- N syntax for begin
|
|
* and end year values. (Monte)
|
|
* - 1.2 added support for yyyy-mm-dd syntax for
|
|
* time value. (Jan Rosier)
|
|
* - 1.3 added support for choosing format for
|
|
* month values (Gary Loescher)
|
|
* - 1.3.1 added support for choosing format for
|
|
* day values (Marcus Bointon)
|
|
* - 1.3.2 support negative timestamps, force year
|
|
* dropdown to include given date unless explicitly set (Monte)
|
|
* - 1.3.4 fix behaviour of 0000-00-00 00:00:00 dates to match that
|
|
* of 0000-00-00 dates (cybot, boots)
