Tick

Remarks

Every packet is stamped with one, and wall-clock time never appears in a packet. Snapshots, input, interpolation targets and history rings are all keyed by tick, so two machines that disagree about what time it is still agree about what happened when.

It wraps, and the comparisons know it. A UInt32 at 60 Hz lasts a bit over two years of continuous uptime, which is long enough that no one will ever see it and short enough that somebody would eventually. Comparison is therefore by signed distance — (int)(a - b) — which gives the right answer across the wrap as long as the two ticks are within about 2^31 of each other, and they always are.

There is deliberately no < operator and no IComparable`1. Modular comparison is not a total order: with three ticks spread far enough apart, A is after B, B is after C, and C is after A. Sorting by it would be undefined behaviour, so the type refuses to look sortable and says IsAfter instead.
