need flexible output average capability

[jiandewang]

Is your feature request related to a problem? Please describe.
MOM6 uses FMS to manage its output frequency and time average.
If model IC date is 03Z and we want daily averaged output, then the 1st daily averaged output will be 03Z-03Z but what we want is 03Z-24Z for the 1st day. So we believe current FMS is based on forecast hour to do the averaging, not the clock (i.e not the end of the day, or month)

Describe the solution you'd like
would like to see a flag that to write out files based on the clock and not just from forecast hour.

Describe alternatives you've considered
