Formatting a duration

When a command requires a duration parameter, you format it as a number followed by a unit. The unit can be one of the following: s for seconds ; m for minutes ; h for hours ; d for days ; w for weeks. For example, 5d stands for five days, and 1w stands for one week. You can also combine them — 1w3d means one week and three days.
