I'm also out of the loop but after some research, 0473 seems to be a TikTokism meaning "hug me, please." I would assume that this code uses octal notation, hence GP doing their math in octal, but the sources I've turned up describe codes with digits illegal in octal, so I don't really know.
Maybe RFC 9759, which is referenced in the article "HTTP offload is a dumb great idea whose time has come"?

OP apparently noticed that two weeks is almost 20480 decimal = 050000 octal minutes, just 320 = 0500 minutes in fact.
