The Date function returns the current date in TDateTime format. When the above code was compiled and executed, it produced following result: Current time : 18:33:08 The following example shows how to get the current time: program TimeDemo uses sysutils begin writeln ( 'Current time : ', TimeToStr (Time ) ) end. Pascal's TimeToString function gives you the current time in a colon(: ) delimited form. However, the actual name and workings of these functions are different for different compilers. Pascal also provides powerful tools for date arithmetic that makes manipulating dates easy. Dates are so much part of everyday life that it becomes easy to work with them without thinking. Most of the software you write needs implementing some form of date functions returning current date and time.
