For example, “<literal>1h 30m</literal>” specifies the same time as “<literal>90m</literal>” or “<literal>5400s</literal>”. A value without a suffix means seconds. It is recommended to always specify a suffix. </para> <para> Some of the time intervals can be specified only with a seconds resolution. </para> </section> </article>
