I was wondering when someone would ask. It's the code to infer the upper 2 bytes of the timestamp from the player position packets. If you get a timestamp of say 0x1234 and you know the current server time should be 0x55551241, then you can infer the packet timestamp is 0x55551234. There are 2 other much-less-common cases, where the packet timestamp is wrapped ahead or behind. When last I looked, MERV only handled one of them--I forget which. I discussed it with Snrrrub--who I believe ripped most of the VIE source that Catid needed--and he disagreed with me. The argument led to a complete breakdown of propriety between us (which I regret). It's a very small point, but can cause wildly out-of-sync position packets in the bot every 65536 SS ticks (655 seconds), which any decent core/client should simply drop. Visually, there would be one missing packet, so it would not result in anything noticable. Again, it is a very small point.
