What? Maintenance at 8 PM?? Can't nearly inconvenience enough people at that hour! Of course it's 08:00 (as in AM)! 
OK, Richard - how about those people who write 24:00 for midnight?? I actually found a script once that tried to trigger something at 24:00 instead of 23:59 or 00:00. "Time" as we refer to it is a measurment of its passing - at midnight of the current day, no (reasonably measurable) time has passed, so it is 00:00.
If you don't think time is important, consider the $$$$$$$$$ spend in 1999. 
I had a moment this morning when I found that the time on my cell phone was off by 4 minutes.. It is supposed to sync with the carrier's time base - does this mean that time at one of the largest telecoms in the US has bad time sync?

PS - stick to the good meds!
