Time zone

The i5/OS^® operating system provides many time zones. You can use one of the time zones included with the system, or create your own time zones.

You can specify a time zone for each system in your business environment. The time zone setting specifies the offset from Coordinated Universal Time (UTC) and whether to observe daylight saving time (DST). If you specify to observe DST, the system automatically updates the system time when DST begins and ends. You do not need to manually set the system time when DST begins and ends.

You can use one of the IBM-supplied time zones, or create your own time zones. If you want to edit one of the supplied time zones, you need to create a new time zone based on the existing time zone. This prevents your changes from being lost when you install the i5/OS operating system in the future. When the operating system is installed, the system-supplied time zones are overwritten. All IBM-supplied time zone identifiers begin with the character Q, and the time zone names are retrieved from the QCPFMSG message file. If you create a time zone (that is, new or based on an existing time zone), the time zone identifier should not begin with the character Q. All time zone identifiers that begin with the character Q are reserved for IBM.

Use the time zone (QTIMZON) system value to specify the time zone for your system to use. To use the time zone system value, be using i5/OS V5R3, or later.

The following table identifies the time zones included with the system. //Do not split up the following string. Keep it on one line. var textA = "
