Current time - datetime and datenum

Hi, I am using the time as part of my plot, but I need to get the current time, just the time, not the data. I know that if I use the diatomite function ('now') will give me the current date and time, but my data is only with time, it doesn't have the date. Then I'd convert it with the datenum. Is there any function that could give just the current time?

now    Current date and time as date number.

  FLOOR(now) is the current date and REM(now,1) is the current time.
