[MITgcm-support] mnc output problem-multiple time step

[Abbas Dorostkar]

Dear all,

Recently, I am getting mnc output with different time steps of 420 and 360
sec though I have defined the dump frequency as 400 sec. I have not changed
my set up but I have no clue why I get this problem. Please let me know if
you have any idea .

Thanks

Abbas
