/*Date picker functions*/
//NOTE: This was used because the .Net built in Calendar created all sorts of
//		problems when being used with a non Internet exploror browser.

// modified by BG to use ISO 8601 dates (YYYY-MM-DD) on 2003-05-16 :^)
// Modified to rely on mouse position and to go back to MM/DD/YYYY
// Relies on the fact that there's 2 spans with the names startpick and endpick, and needs the client id's of
// startDateText and endDateText

// Title: Timestamp picker
