DAYLIGHT SAVINGS TIME WARNING:

If you use this DLL and have daylight savings time enabled on your system, when the system clock is adjusted for daylight savings time your control and acquisition loops will be affected:

In the spring, when clocks shift forward, DAQFactory will think it was hung for an hour. This will cause a Timing Lag error on all acqusition loops. Serial and Ethernet communications may throw a timeout error even though comms are fine. Any script that is looking for timeouts, or watchdog scripts may trigger since it will appear as if nothing happened for an hour.

In the fall, when the clocks shift backwards, any loops that happen to be waiting (for example in a delay(), or even simple Channel Timing) will likely hang for one hour while the clock comes back to future time. This means an hour of dead time. Worse, if a loop happens to not be in the delay() at the time of the time shift, it will run normally, so which loops hang for an hour and which run properly is completely random.

We strongly recommend turning off daylight savings time if you wish to use this DLL and the Windows system clock.
