Using the Calendar
To specify a future time to the nearest hour, click the calendar icon. The calendar allows you to select a date first, then a time.
Entering a Time Manually
Alternatively, enter the time to the nearest minute using this syntax:
year-month-day hour:minute
The year must be entered as four digits and the month and day each entered as two digits with leading zeroes for single-digit months. For example, enter February 12, 2011 as:
2011-02-12
Hours and minutes must each be entered as two digits with leading zeroes for single-digits, using the 24-hour clock. For example, enter 4:17 AM as:
04:17
