Modifying Daylight Saving Time Settings
If you want to change the DST rules string, you can add an entry to the configuration options for LabWindows/CVI in the registry. Set the entry name to DSTRules and set the entry value to the modified DST rules string.
You can set configuration options for the LabWindows/CVI development environment and set configuration options for the LabWindows/CVI Runtime.
LabWindows/CVI ignores a modified DST rules string for executables or DLLs you build when you select Instrument driver only for Run-time support in the Target Settings dialog box. The instrument driver support run-time library does not contain code to read the LabWindows/CVI configuration options.
Suppressing Daylight Saving Time
You can suppress daylight saving time by modifying the DST rules string as follows:
":(1900)010102+0:010102-0"
Starting Year in Daylight Saving Time
If you start the year in daylight saving time, use the following descriptor as the first descriptor in the rule:
"010100-0"
For example, the following rule specifies that the year starts in daylight saving time:
":(2006)010100-0:040100+0:110100-0"
