Int 21H, AH=2CH

Version

1 and higher

Brief

GET SYSTEM TIME

Family API

Input

      AH = 2Ch

Return

CH = hour

      CL = minute
      DH = second
      DL = 1/100 seconds

Notes

 on most systems, the resolution of the system clock is about 5/100sec,
        so returned times generally do not increment by 1
      on some systems, DL may always return 00h
