On RTEMS the TZ environment variable can be used to set the time zone information and the dates at which to switch between standard and daylight-savings time. The following example applies to Chicago for the daylight-savings times rules in effect for 2011:
epicsEnvSet TZ "CST6CDT,M 3.2.0,M 11.1.0"
This sets the standard time name to CST and the daylight-savings time name to CDT. Standard time is 6 hours behind GMT. Daylight savings begins on the 0th day (Sunday) of the second week of the third month and ends on Sunday of the first week of the eleventh month.
The command
epicsEnvSet TZ "CST6"
is applicable for Saskatchewan which stays on Central Standard Time all year.

Title:
EPICS_TIMEZONE and osi*Time providers not documented
Status in EPICS Application Developers' Guide:
New
Bug description:
There have been a number of changes to the environment parameters
since section 7.8 was last revised.
There needs to be documentation on the osiClockTime and osiNTPTime
time providers, and the use of the EPICS_TIMEZONE parameter on
vxWorks, and how this works on RTEMS.
