Clock

The clock is used to return the current time as DateTimeImmutable. There is a system clock and a frozen clock for test purposes.

Info

You can find out more about clock in the library documentation. This documentation is limited to bundle integration.

Testing

You can freeze the clock for testing purposes:

when@test:
    patchlevel_event_sourcing:
        clock:
            freeze: '2020-01-01 22:00:00'

Note

If freeze is not set, then the system clock is used.

PSR-20

You can also use your own implementation of your choice. They only have to implement the interface of the psr-20. You can then specify this service here:

patchlevel_event_sourcing:
    clock:
        service: 'my_own_clock_service'

Symfony Clock

Since symfony 6.2 there is a clock implementation based on psr-20 that you can use.

composer require symfony/clock

patchlevel_event_sourcing:
    clock:
        service: 'clock'
