runTaskTimer question

Consider the following (approximating time)

Code:java

 
runnable.runTaskTimer(plugin, delay, period);
runnable.runTaskTimer(this, 12000, 36000);
 

Does this run once in ~10 minutes and again every ~30 minutes after. Or does it run once in ~40 minutes and every ~30 minutes after?

Or to phrase differently, does the delay indicate the time of the first run or the time when the first count down begins and the first run is only after that countdown is finsihed?

 

Delay determines the duration until the first time the task is ran, from that point it uses the 'period' for every next run.

so in your case. it waits 10 minutes to run the first time
and then every 30 minutes it repeats itself

 

Well, that's how I interpreted the API docs, but for some reason the first run doesn't occur for me. I was looking through the CB code to confirm but I can't find it.
