24 hour timer help

Hey everyone I got this 24 hour timer it came with my 400w mh/hps system but I don't know how to set it and the instructions just say align segments to on time does anyone know how to set these?This is the only thing I can find right know its not letting me post a picture.http://www.ebay.com/itm/170819262999?ssPageName=STRK:MEBIDX:IT&_trksid=p3984.m1952.l2649#ht_5915wt_1100

on the edge there should be little things you can press down, each one you have pressed down usually corresponds to about 15 mins so if you want 12/12 push half of them down
set the time to the time you have locally

Yea I saw those so but idk my time in 24hour cycle or whatever but I found this conversion chart is this correct? http://en.m.wikipedia.org/wiki/24-hour_clock

yeah that is correct
just look at your phone, see the time and set up no need to over complicate things

Lol yea I know and just one more question on the side of the timer thers a switch and it has two options one is a clock and one is an I do you know what these are for sorry bout all the ?'s.

the 'clock' one turns on the timer and the other one keeps it on 24/7

Ok thanks for the help now I'm gonna go set this up later.
