[SAC-HELP] cannot add sac header

[mplasencia at ogs.trieste.it]

Hi,
Please. first check if in your header exist the LOVROK = FALSE,
if yes, change it to TRUE. It permit overwriting

Then. check if the variables KZDATE and KZTIME exist in the header,
you can see the manual for further information using the NZYEAR, NZJDAY,
NZHOUR, ..., NZMSEC, for setting the date and time.

HTH,

Milton
