INTRO

This package provides commands able to start/stop synchronized timers.

Each time a timer is triggered, it executes a user-defined command. Timers are triggered at regular intervals, and are aligned (synchronized) with the system-clock.

• timers can be triggered when the system-clock strikes the hours ( or the half-hours, or more ... read below)

For full details read the documentation :

• SyncTimer Reference

   set t1  [SyncTimer::every "10 secs" "00:00:00" { puts "[clock format [clock seconds]]" }]
