omnifaces

 - 

Available since OmniFaces 3.6

The builtin managed bean #{now} returns you the java.time.temporal.Temporal instance representing the current time in server's default time zone.

The implementation is provided by org.omnifaces.cdi.config.DateProducer.TemporalDate which is essentially written as a CDI proxy for java.time.ZonedDateTime because it's a final class.

Demo

Raw Temporal#toString() value of #{now}: 2023-03-21T16:20:07.907988+01:00[Europe/Amsterdam] - this should represent same format as java.time.ZonedDateTime

Formatted using of:formatDate() function: 2023-03-21 16:20:07

As java.time.Instant: 2023-03-21T15:20:07.907988Z - this should represent UTC

Formatted using of:formatDate() function: 2023-03-21 15:20:07

As java.time.ZonedDateTime: 2023-03-21T16:20:07.907988+01:00[Europe/Amsterdam]

Formatted using of:formatDate() function: 2023-03-21 16:20:07

As epoch time: 1679412007907
