0:46Ch                   Long integer with Timer Counter

Length: 4 bytes

Holds the number of ticks needed to reflect the current time in a 4-
byte integer. Every timer tick (18.2 per second) activates INT 08h,
which increases this value by 1. After this value reaches midnight
(1800B0h), it is set to 0 and the byte at 0:470h is set to 1.

                                                                          

Notes:         Use INT 1Ah, Service 00h, to obtain this value. Note
that doing so clears the overflow flag at 0:470h.
