Reading a file, searching for a pattern, and returning a line. Im a little stuck.

[MasterChef]

Hey guys, I will first say i am brand new to this forum. My problem is that I have a log file (see sample of it) I want to be able to determine if the await column returns all 0.00, then I would return the date and time it occurred. Some help on this would be greatly appreciated!
