get hour from TTime object without using DecodeTime method

Is it possible to retrieve hour from TTime object in 开发者_运维百科c++ builder

without using DecodeTime(args), by doing calculations ?

The HourOf function returns the current hour of a TDateTime value.

// get hour from the current time
int Hour;
Hour = HourOf(Now());

Have a look at the DateUtils unit, which include lots of useful functions for handing dates and times.
