I have a text file that looks like this:
Start find in flight queries
2018-03-05 15:50:02,069:INFO:######################################
Start find completed queries
2018-03-05 15:50:02,070:INFO:Starting new HTTPS connection (1): server060
2018-03-05 15:50:02,083:DEBUG:"GET /queries?json HTTP/1.1" 401 0
2018-03-05 15:50:02,084:INFO:Resetting dropped connection: server060
2018-03-05 15:50:02,095:DEBUG:"GET /queries?json HTTP/1.1" 200 19059
2018-03-05 15:50:02,099:INFO:######################################
Start find in flight queries
The date and time changes every 5 minutes. I need to copy the very last date and time to another file. In this example its 2018-03-05 15:50:02.
Any suggestions are appreciated. I have used a little regex in the past but not good at it.

tac + grep solution:
tac input.txt | grep -Eo -m1 '^[0-9]4(-[0-9]2)2 [0-9]2(:[0-9]2)2' > last_date.txt
