How to use a single-chip timer to prepare a clock program

"1. The program structure adopts the main program and interrupt service subroutine structure 2. Timing interrupt program Timer 1 is in mode 1, 16 bits, and is interrupted once in 10ms 40h10ms counting unit 41h second counting unit 42h minute counting unit 43h hour counting unit Timing mode 1 is 10ms: thx = 0ech, TLX = 78h Mode 0 is 10ms: thx = 63h, TLX = 18h 3.
