clarification of timers

[bufferofnewbies]

I started investigating the quest:starttimer and quest::stoptimer effects in some of my tests, but I cannot seem to find any information about the dbase fields.

Been looking over Angelox's release at the timers table to help narrow down the possibilities. The wikki has no viable information, at least from a search for 'quest timer' or 'timer' that I was able to locate.

Anyone able to verify the range/ use of each field?

char_id: I assume this is the id of the npc calling the quest.
type: no clue as to what this field references
start: not really sure what this is for, perhaps last time it was activated?
duration: how many seconds the timer lasts? if so, why is it set in the quest?
enable: still no idea, but all I have seen for references are set to 1. Im guessing this is a condition for global triggers?

Any help would be appreciated, even if its just a link to some part of the wikki I happened to miss.
