The built-in Date object will return the system time and date, in pieces. The expressions for the time, if you don't rename the object to something other than 'Date', are Date.GetHour, Date.GetMinutes, and Date.GetSeconds. It also can return the date as a string.
If you are willing to use python, you can import the time module and use the time.time() function to get system time. That module also has a number of other functions for working with times.
