The difference between "NORM" and "TIME" modes in the offset is that in "NORM" mode, the "off" setting will not take effect until you turn the mix off. In "TIME" mode, the offset will hold as long as the "Stop" delay value. So if you have an offset mix with a "Start" delay of 1.0 and a "Stop" delay of 5.0, then the mix will turn on 1 second after you activate it with the switch, hold for 5 seconds, and then move the servo to the "off" position you set in the "offset" section.

In "NORM" mode, the "Start" and "Stop" delay settings take effect only upon switch activation, so with the same settings as above, the offset takes place one second after you turn it on with the switch, and then returns to normal 5 seconds after you turn it on.

You can also cascade up to 4 offsets on the single switch. You just have to make sure you set the delays so that they take place with the proper amount of delay between them. In "NORM" mode, they will then turn off in sequence if you set "STOP" times in their delays. In "TIME" mode, they will hold for the amount of time in the "STOP" section and then return to the previous setting...and then step backwards, according to the delays you have set.
