But the idea of having multiple arguments is that you can write for example “1h 30m”, of course, this is not important is you can just as well write “90m”, and in case where the calculations are that simple you can use expr(1), but implementing it didn't really complicate anything and brings compatibility. Waits shorted that 1s is useful in things like rc-scripts that need to wait for a short period. And longer waits are useful in cases like if you are setting up a simple alarm if you want to take a short rest, or if you have a lot of things running in different terminals (because you want to see the output of each) but you don't want all of the to run a the same time.
