Description

For writing component restarts, there are several current options:

• RESTART_N to write at regular frequency
• restart_fh for med, ocn, wave, ice components to write at flexible forecast hours
• restart_interval for atm to write at regular and flexible forecast hours

Then, internally setting these options to get the restarts you want varies by component + if restarting + if iau_offset for atm.

Solution

Use startTime as the base to simplify translation of forecast hour to calendar date (with or without restarting or IAU)

Alternatives

Continue as is as changes require downstream updates and effort
