Appendix D Time Zones

This appendix contains a list of commonly used time zones and the TZ environment variable strings that correspond to these time zones. You use the TZ strings in the SNMPUDC.NET.SYS file to allow SNMP to adjust to specific time zones.

In Table D-1 “Time-Zone Codes”, column 1 contains the time zone name followed by the Daylight Savings time zone name, if appropriate. Column 2 lists the geographic locations associated with this time zone. Column 3 contains the TZ environment variable string for the time zone.

To set the TZ variable to a specific time zone, use the MPE SETVAR command. For example, if you want to specify the Pacific Time Zone in the United States, enter the following MPE command:

setvar TZ "PST8PDT"

In the TZ string above, PST represents the time zone abbreviation for Pacific Standard Time, 8 represents the difference in hours between Pacific Standard Time and Greenwich Mean Time (GMT), and PDT represents the Daylight Savings time zone abbreviation for Pacific Daylight Time.
