conf_phys.F @ 1524

Last change on this file since 1524 was 1524, checked in by emillour, 9 years ago

All GCMS:
More updates to enforce dynamics/physics separation:

get rid of references to "temps_mod" from physics packages;
make a "time_phylmdz_mod.F90" module to store that
information and fill it via "iniphysiq".
