Hyundai Repair: hyundai accent clock, hyundai accent, dash clock

Question
Hi I have a 2001 Hyundai accent bought used with no car manual and I need to change the dash clock to the correct time.  I've tried combinations of buttons and I was able to get it to change once but now I can't figure out what I did to get it work.  So I know it works but I'm not sure what the combination is to get to change.

Thanks!

Answer
Holding in the H button should cause the hours to scroll forward in time.

Holding in the M button should cause the minutes to scroll forward in time.

Depressing the R button should cause the clock to reset to the nearest hour.

If the buttons do not allow you to adjust the time, you probably need a new clock.  This is one of the modes of failure of the clock.
