task completion check UTC instead of local timezone

[Dan Kortschak]

When a task is completed it can be marked as such. The code, correctly, checks to ensure that a task is not being marked as completed before the current time. Howvever, the current time is taken (apparently) from UTC and not from the current local timezone. This means that it is not possible to mark a task as completed in the eastern hemisphere before the UTC offset of the timezone, i.e. we must be after the threshold in UTC.

If I complete a task before 9:30am and attempt to mark it as completed I am met with: "Completed date cannot be in the future".

This appears to be due to an optimisation in cal_comp_util_compare_time_with_today which only compares time (without timezone) if the time is only a date.
