Ok so I noticed this a while ago but thought it was just my browser messing up, so I ignored it. It's been seen again so here's my report on it:
For some reason recently I have been seeing old posts that have new replies getting the dates mixed up (see below), and it has messed up in a way that sometimes I see people's posts from months ago answering questions posted this week, for example, below is a snip of a conversation between
g33kteacher, and it seems that
g33kteacher posted their reply a day ago, but Alex replied in November!
