Unfortunately these different configurations have little consistency in > units - eg some are in milliseconds, some in seconds, and some in minutes. > This makes it difficult for users to configure, since they have to always > refer back to docs to remember the unit for each property. > The proposed solution is to add an API like {{Configuration.getTimeDuration}} > which allows the user to specify the units with a postfix. For example, > "10ms", "10s", "10m", "10h", or even "10d". For backwards-compatibility, if > the user does not specify a unit, the API can specify the default unit, and > warn the user that they should specify an explicit unit instead. -- This message is automatically generated by JIRA.
