Inputs/Outputs
Reset

Controls the initialization of the internal state of the VI. The default is FALSE.
Time Target (s)

Set Start Time (s)
—
Uses the current time or a time offset from 12:00 a.m., Friday, January 1, 1904 [01-01-1904 00:00:00] as the start time instead of the time this VI first ran. If the value is 0, the Express VI uses the current time as the start time. The Express VI uses any other value as the number of seconds offset from 12:00 a.m., Friday, January 1, 1904 [01-01-1904 00:00:00]. For example if the value is 1, the Express VI measures the elapsed time since 12:00:01 a.m., Friday, January 1, 1904 [01-01-1904 00:00:01]. You can wire this input to the Present (s) output of another Elapsed Time Express VI to get this value.
