this isn't really an issue that affects anything in any way, just a display glitch

so I scanned this nice metallic owned by a rank 400+ inactive, so I immediately took it, added my own structures and use 5 time vortexes to get the production up....then I noticed how old it said the colony was.....so I understand why it'd say the 5 days part, it's because of the vortexes, but what's with the 5 hours? I took this screenshot about 10 minutes after I actually scanned the planet...
