if you look at the 'impl_handleURI' function in 'calendar-component.c', the standard function 'time_from_isodate' is used to parse 'startdate' and 'enddate' values. the 'time_from_isodate' documentation states the string must be a Date/time value in ISO 8601 UTC format.
in other words, the date string must include the time and be in UTC. the format is also specified in the upstream of bug #35167: http://bugzilla.gnome.org/show_bug.cgi?id=162305 -- Clicking on date in calendar applet open previous date in Evolution https://launchpad.net/bugs/42115 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
