How do I make UniBasic use the new daylight savings time rules on SCO OpenServer 5?
The TZ environment variable should be set to include the new daylight savings time starting and end dates. In the United States, this requires adding the string “,M3.2.0,M11.1.0” to the end of the normal TZ value. For example, a Pacific timezone setting of “PST8PDT” must be changed to “PST8PDT,M3.2.0,M11.1.0”. The TZ value can be changed in the user profile or in the file /etc/TIMEZONE. If the value is changed in /etc/TIMEZONE, the system must be rebooted to use the new value.
