A set of system variables that indicate the difference in time between local (operating system) time and Greenwich Mean Time (GMT).
&ZGTIMEZ, &ZGTIMEZ1, &ZGTIMEZ2, and &ZGTIMEZ3 are system variables that indicate the difference between local time and GMT.
plus or minus HH.MM
plus or minus HH:MM
plus or minus HHMM
plus or minus nnnnn, where an integer is hundredths of a second since midnight
Example: &ZGTIMEZ
&TIMEDIFF = &ZGTIMEZ
Note: Each access to &ZGTIMEZ3 causes the system to re-fetch and synchronize time with the operating system, to format the result to microsecond accuracy. Unless you require this level of accuracy, you should avoid using the &ZUTIMEZ3 option, to reduce unnecessary overheads.
