Mars PEM: The date and time are redefined at the end of PEM to write the file "restarfi_evol.nc". Like so, the next GCM runs can restart at the date and time given at the beginning of the simulation since the PEM is only progressing by step of one Martian year. JBC

51	c subject:
52	c --------
53	c PROGRAM useful to run physical part of the martian GCM in a 1D column
54	c
55	c Can be compiled with a command like (e.g. for 25 layers)
56	c "makegcm -p mars -d 25 testphys1d"
57	c It requires the files "testphys1d.def" "callphys.def"
58	c and a 'run.def' file (containing a "INCLUDEDEF=callphys.def" line)
59	c and a file describing the sigma layers (e.g. "z2sig.def")
