If you start, then pause a timer, the counter still appears to tick down to 1, then "halts" there. As soon as you resume the timer, it ticks the last second off the clock, and executes the command.
For example:
/timer 1 10 /echo -a *** test
* Timer 1 activated
/timer1 -p
* Timer 1 paused
[The timer is paused a second or two after its started]
[Wait 10 seconds or so]
/timers
* Active timers:
* Timer 1 1 time(s) 10s delay /echo -a *** test (GamesNET)
[Wait another 10 seconds or so (just to be sure)]
/timer1 -r
* Timer 1 resumed
*** test
* Timer 1 halted
[The last bit happening within a second of me resuming the timer]
