SYSTEMTIME_TO_DCTIME
 | Outdated function This function is outdated. Use the function SYSTEMTIME_TO_DCTIME64 instead. |
The function converts a structured Windows system time variable of type TIMESTRUCT to a 64-bit distributed clock system time variable of type T_DCTIME. In the event of a conversion error the function returns the value zero.
FUNCTION SYSTEMTIME_TO_DCTIME: T_DCTIME
Inputs
VAR_INPUT
in : TIMESTRUCT;
micro : WORD(0..999); (* Microseconds: 0..999 *)
nano : WORD(0..999); (* Nanoseconds: 0..999 *)
