Configuration reference

Configuration properties use the quarkus.clock prefix.

Property Default Notes

Property	Default	Notes
`quarkus.clock.type`	`system`	One of `system`, `fixed`, `adjustable`. Enum values are matched case-insensitively.
`quarkus.clock.fixed-instant`	(empty)	Required when `type=fixed`. Must be a valid ISO-8601 instant (for example `2000-01-01T00:00:00Z`).

quarkus.clock.type

system

One of system, fixed, adjustable. Enum values are matched case-insensitively.

quarkus.clock.fixed-instant

(empty)

Required when type=fixed. Must be a valid ISO-8601 instant (for example 2000-01-01T00:00:00Z).
