Function Explanation

Time and Date to Bool, Bit String, Integer, Real Number and String
The rule for the conversion of the time and date into the bool, bit string, integer, real number and
string is the same as that for the conversion of the unsigned integer into bool, bit string, integer, real
number and string. Refer to section 8.13.5 for details.

Time and Date to Time and Date

The time and date data can be converted to each other. And some instructions are shown
below.
The rule for the conversion of the time and date data into the time and date data is the same
as that for the conversion of unsigned integers into unsigned integers. The units must be
uniform during the conversion. The unit of TIME is ns (nanosecond) and the unit of others is
Time s dates _TO_* **
