(IFRC(arg))
Where arg is a value that has either a TIME or DATETIME data type, IFRC returns the current thousandth of a second. For this function to work correctly, the TIME format must be set to include thousandths of a second.
In the following example, the value of vifrc is 123.
SET TIME FOR HH:MM:SS.SSS
SET VAR vifrc = (IFRC('12:15:30.123'))
