Hi there, this is a shot in the dark, but I'm curious if you know how the current server time is translated into the readable format of "Day X HH:MM"? I've been trying to build a tool that lets me see what the current server time is, and so far I've been able to get the 'Current Server Time' from pinging the server, but it comes back as a number that i cant figure out how to translate it. For example, im getting 90219 which apparently is supposed to be "Day 3, 18:13"
