Create a system variable which contains the schedule timestamp

Hello,

a system variable that contains the timestamp of the schedule (not the actual fired time) would be very useful. Currently, workarounds are needed to store this timestamp. In a data warehouse (lakehouse) environment, this information is very helpful.

Example:
A Pipeline is scheduled two times a day: 1430 and 2330
This timestamp would be useful as a variable. (At least i could not find it)
