Thread: unable to change KZTIME in SAC

Hi Anupam,
Please read details of SAC header variables in the manual:
https://ds.iris.edu/files/sac-manual/manual/file_format.html

KZTIME is a derived variable:
KZTIME A Alphanumeric form of GMT reference time. Derived from NZHOUR,
NZMIN, NZSEC, and NZMSEC.

Which means you have to change NZHOUR, NZMIN, NZSEC, and NZMSEC header
variable if you want to change KZTIME.
