The MINUTE function returns the minute part of a value.
The argument must be a time, timestamp, or a valid character string representation of a time or timestamp that is not a CLOB, LONG VARCHAR, or XML value. The result of the function is a large integer. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
