FILETIME_TO_SYSTEMTIME

FILETIME_TO_SYSTEMTIME 1:

The function  "FILETIME_TO_SYSTEMTIME" converts time from FILETIME format  into the "readable" SYSTEMTIME format. The conversion fails if the most significant bit of 64 bit file Time variables is set. In this case the TIMESTRUCT member variables have the value zero.

FUNCTION FILETIME_TO_SYSTEMTIME: TIMESTRUCT

TIMESTRUCT 

VAR_INPUT
    fileTime        : T_FILETIME;
END_VAR

fileTime:: Time to convert in FILETIME format

Example in ST:

PROGRAM MAIN
VAR
    fbSystemTime     : GETSYSTEMTIME;
    timeAsFileTime   : T_FILETIME;
    timeAsSystemTime : TIMESTRUCT;
END_VAR
(* program code *)
fbSystemTime( timeLoDW =>timeAsFileTime.dwLowDateTime , timeHiDW =>timeAsFileTime.dwHighDateTime );
timeAsSystemTime := FILETIME_TO_SYSTEMTIME( timeAsFileTime );
