I joined an IRC channel the other day and said Good CET Morning. Got an immediate reaction.
#OT What is so CET about it?
#OT was the first thing that somebody said.
Next up, they gave me a link to someting called UGT
that I had to check out.
An excerpt from the article:
UGT (abbr.): Universal Greeting Time. UGT is convention initially established in #mipslinux on irc.openprojects.net (now irc.freenode.net) but slowly taking over the world. It states that it is always morning when person comes into a channel, and it is always late night when person leaves. Local time of any member of channel is irrelevant. Resistance is futile. Your ass will be laminated. (geoman is exception to this rule - his ass will be fried instead).
