Mel just IM'd me saying "I'll be home at 6:15, will you be ready"(referring to us having our weekly night out). I looked around thinking "hmmm why is she saying this now it can't be more than 4:30... oh wait"
My brain and body are still used to the sun position matching up with the actual hour, rather than the semi arbitrary obsolete congressional/railroad prescribed time... and it's 5:40, not 4:40.
I'll still be ready in time of course, it's just one of those moments when you think "and we still do this why exactly?".
By June 21st, as far north as I live, it'll be 2130 local before full dark.
