ESM4.2 crash in debug mode when starting year is 1978 , write() statement format too restrictive

[nikizadehgfdl]

Describe the bug

Fabien reported that when running ESM4.2 in debug mode with a starting year of 1978 his run crashes like this:

atmosphere_init: current_time_seconds = *********
forrtl: error (63): output conversion error, unit 0, file /proc/174029/fd/2
Image              PC                Routine            Line        Source
fms_esm4.2_compil  000000000ED263A8  Unknown               Unknown  Unknown
fms_esm4.2_compil  000000000ED89EDD  Unknown               Unknown  Unknown

Probably because the current_time_seconds is too large of a number for the print statement in line 209 of atmosphere.F90:

if (mpp_pe() == 0) write(0,"('atmosphere_init: current_time_seconds = ',f9.1)")current_time_in_seconds

Anyway it would be good to increase the number of digits.

The offending code has been in the GFDL system (dev/gfdl) since the 2021.02 release and this has never been an issue before now. I will note the dev/gfdl_am5 branch has had the write statement removed by PR #291.

I'm assuming this is the first time someone is running an AM4-based model sim that is longer than 3.171 years with a branch created in the last 3 years - where an f9.1 would fail to hold the seconds (Time-Time_init).

I can try to get the 2 commits from PR #291 cherry-picked into dev/gfdl for the AM4 models.

Hi @nikizadehgfdl I have cherry-picked the change from PR #291 into the dev/gfdl branch.
