[MITgcm-devel] problem with argument list of adthe_main_loop

[Patrick Heimbach]

Hi Martin,

I haven't looked into this in a long time.
As you see, the "broad" behavior is that
mycurrenttime is kept for ECCO, but not otherwise.

If I remember correctly, I tried a number of ways to "recompute"  
mycurrenttime
within the_main_loop and make it "self-sufficient" (e.g. use  
starttime), but didn't help much.
I think I also tried the other way round, i.e. "force" TAF to keep  
mycurrenttime always,
but didn't help much either.
My hunch is it has to do with the use (or non-use) of the  
cost_averages... routines.

But would have to see your setup in detail ;)
in particular, what's the difference between the two cases.

I had not pursued this further, since it seems stable for most  
applications,
and can be easily changed in case of unexpected behavior.

Cheers
-p.
