No problem.
Hmm, bit of a problem there. The dates in that log are not sortable. They need to have leading zero's in the month and date so that they can be sorted correctly.
Thankfully though, JavaScript as an array reverse function:
The downside of this compared to doing it when you run the command would be memory use. You may need to check how the tac command works to see whether it is more efficient than JavaScript's reverse. If the log isn't that large, it likely won't make any difference.
