The following time units may be used when specifying time intervals:
wdhmsmsThe units may be arbitrarily combined, but their order must be from the largest to the smallest one.
Example 30.2. Time Interval Specification
1w 2d 5h 30m 5s 100ms = 797405100 milliseconds
1h 30m = 5400000 milliseconds
120s = 120000 milliseconds
When no time unit is specified, the number is assumed to denote the default unit, which is component-specific (usually milliseconds).
