Use the Date Format option on the File menu in the Options
dialog box to specify the date format used to display information in date
If you don't include A.M. or P.M. when entering a time, and the default
time format is the 12-hour clock, application sets the time to P.M. unless you
enter a value between 7:00 and 11:59, in which case application sets the time
to A.M. The time format is controlled by Operating System and is set using the
Control Panel application.
You can enter the time and the date in any order or you
can use calendar picker to select desired date and hour:
For example, you
can type 2:00pm 8/14/15 or 8/14/15 2:00pm.
Or select from calendar:
