What time does Alert Composer use in the system.

I would like some help, I found a problem with the compoder alert that was not sent. I checked all the filter conditions to be sent and they are ok. However, I would like to validate information.

have this condition
${TerminationDate} >= TRUNC(SYSDATE)

where the shutdown date must be greater than or equal to the system date. However, the dismissal was approved on 06/17/2024 at 22:36, and this notification was not sent. Could you tell me the sysdate of the alertcomposer, would it be from the system that is configured in HCM or if it is from the server?

Awaiting return.
