The date format in the event list is defined by the NCO_TIME environment variable. The default format is mm/dd/yy hh:mm:ss; for example, 11/12/03 20:13:36. This format is determined by the POSIX strptime function.
To set the default format, using csh, enter the following command:
setenv NCO_TIME %m/%d/%y %H:%M:%S
To set the default format, using ksh or sh, enter the following command:
NCO_TIME=%m/%d/%y %H:%M:%S;export NCO_TIME
See the man page for strptime for details of the conversion specifiers that are available.
