added functions to set a callback to get the current time, which is used
2001-07-02 Damon Chaplin <damon@ximian.com> * e-calendar-item.c: * e-cell-date-edit.c: * e-dateedit.c: added functions to set a callback to get the current time, which is used instead of localtime(). We need this as we have to use our own timezones. svn path=/trunk/; revision=10728
