How to ingest only those lines from the log that start with "date/time"

[mlevsh]

We have logs , where first few lines needs to be omitted from ingesting.
We only need to on-board the events , that start with the date/time in the following format:
"%m/%d/%Y@%H:%M"

Appreciate all the ideas and suggestions.

Here is  the log example (there are also empty lines
before first "#-----------------------------------------" and
after last "#-----------------------------------------"):

      #-----------------------------------------
      #DATE CREATED:  11/02/2021@04:16
      #SUBJECT:       REPORT ON THE GENERAL STATUS OF AUTOSYS JOBS
      #ENVIRONMENT:   CBA
      #-----------------------------------------

      11/02/2021@04:16,CBA,OTHER,CBA_CLIENT_REPORT_BOX,OI
      11/02/2021@04:16,CBA,OTHER,CBA_copy_file_job,OI
      11/02/2021@04:16,CBA,OTHER,CBA_ABC_SCHEDULER_BOX,OI
