If zones are not advancing, then 1) Clock motor is not rotating dial > replace clock motor, 2) on-off trippers are worn down > replace trippers, 3) or the day skipper is set to skip all days and all skipper pins are pushed down, 4) or sprinkler valve is bad.

The sprinkler timer dial rotates each 24 hours. The trippers cause sprinkler head to turn on zone 1 for example. Zone 1 waters until the dial rotates to part of dial with no tripper. Without a tripper on the dial, the timer turns off circuit to sprinkler. At this point, the sprinkler valve mechanically advances to zone 2 and waits for timer to turn off again. The timer does not advance sprinkler to next zone > the sprinkler valve is designed to advance each time circuit turns off. The timer just turns on and off. When next tripper rotates around, the timer turn on the circuit and zone 2 begins to water.

You have Intermatic sprinkler timer.
The silver pin inserts into the yellow dial at 12:00 midnight, and it rotates the skipper wheel.
Skipper wheel is necessary only if you want to skip certain days of the week, otherwise the timer cycle repeats each 24-hour period.
To skip a day, the skipper pin is pushed down for that day. Leave skipper pin up for days you want to water.
