Configuring Durations

share [gp] share [fb] share [tw] share [pin] contribute

The time based configuration properties of containers and beans support plain english, such as:

• "1 hour"
• "27 minutes"
• "10 seconds"

For convenience it is possible to specify a compound form, such as:

• "3 days and 2 hours"
• "1 hour, 45 minutes"
• "15 minutes, 23 seconds, and 10 milliseconds"

Spaces are also optional between the number and the time unit, which can be nice when using the abbreviated forms:

• "1hr"
• "27m"
• "10s"
• "3d and 2hr"
• "1hr, 45min"
• "15m, 23s, and 10ms"
