Maybe something like
---8<---
unless defined? $scheduler
$scheduler = OpenWFE::Scheduler.new
$scheduler.start
#...
end
--->8---

The methods schedule(), schedule_at() and schedule_every() each
returns a 'jobid' when called.
You can do :
---8<---
jobid = $scheduler.schedule_every("10s") { puts "hello !" }
#... a bit later
$scheduler.unschedule(job_id)
--->8---
I will document that a bit more.

It's true the schedule_at() will trigger task in the past immediately
and not schedule them.
But should we consider that a bug ? It's a bit weird to have absolute
dates in your program. Why don't you use a [cron] schedule() ?
---8<---
$scheduler.schedule("0 23 1 * *") { do_the_database_task() }
#
# will trigger this task on the 1st of each month at 23:00
--->8---
For more explanation on the cron configuration type "man 5 crontab" in
your favourite unix box or get there :

Hope this helps, best regards,
