[MITgcm-support] rbcs time line

[Aurelien L Ponte]

Hi all,

Imagine I want to relax simulation s1 toward simulation s2.

Both have same time step (90s)
outputs of s2 are every 1800s (20 iterations)
relaxation files (from s2) are rbcs_T.0000000000, rbcs_T.0000000020 ...

Could anybody please confirm that I need to prescribe rbcsForcingOffset=900 in order to have
the right synchronization between run s1 and s2 ?

thanks

aurelien
