Well, it's not in the bugs thread because it isn't a bug. The game is designed to run smaller increments when something is happening. However, its seems odd that you have had 5 second increments for an hour. Could you switch on SM mode and look in the events log (Ctrl-F3) to see what is causing the short increments?

I looked in the events log in SM mod when the 5-sec increment started, and I got a message saying something like "NPR must be fighting somewhere". I did not have a save before the return to normal, but I have one after my AMMs killed the mines and the return to normal time increment. I will look at my save tonight (french time) and see if I can get the exact message.
But I'm 100% sure that 5-sec increment started when I pass near the mines while pursuing an ennemy fleet, and go on for more than 1 in game hour until I come back and kill these mines. As the 5-sec increment stopped the very increment after the mines where killed, I do not think it could be a coincidence with another NPR battle elsewhere.
I fully understand that the increment goes on 5-sec when I started approaching the mines, but it seemed odd to me that it didn't stop when I was far away from them.
Working in computer science myself, I thought it could be a problem of unactivated or forgotten trigger to stop the 5-sec increment when you go out of range of the mines, so I posted it in the bug thread.
'Technical' data:
fleet speed: 8.000 km/s
distance from the mines (outpost #1) to the far point reach (outpost #2) 27.000.000 km
distance from the mines when 5-sec increment started: between 5 and 7.000.000 km, and I did not go near than 4.500.000 km from the mines, I didn't remember which sensor spotted them. I can check if it could be interesting.
