Original War has its own time measuring mechanism. The smallest unit of time is called a tick.
Tick's duration isn't necessarily constant but quantized. It can be changed using the speed slider while playing.
Using the normal speed, one tick lasts 1/35 of a second. It's the same in a multi-player game where you have no speed slider.
SAIL and time
In SAIL time can be expressed using plain integers and will be treated as number of ticks:
Above will wait 35 ticks, that is 1 second if you use the normal speed.
But it can also be expressed using special notation with a dollar sign. It's then a separator between minutes and seconds:
Above will wait 1 minute and 5 seconds but there is a caveat: this is true only if you use the normal speed!
SAIL interpreter finds X$Y notation and applies: 35 * (60 * X + Y). Nothing less, nothing more.
