### Details

:::note
 The property requires the [recurring](guides/extensions-list.md#recurring) extension to be enabled.

:::note

Watch out! The option is intended for 'newborn' schedulers with no existing recurring events.
Applying to the scheduler with already existing recurring events will break them.
 
:::
- If the option is enabled, timestamps of events are stored as UNIX time.
- The option is available from version 3.5.
