Time played randomly turns negative

[ghost]

Every now and then, someone's "time played" on my server will turn negative, and then it will count back up into the positives. Any way to fix this?

I can confirm this issue with my own port of Evolve (Linux x86_64 server here), I will be investigating this issue further and try to come up with a solution.

My friend and I have come up with a fix, we think the issue is due to the fact that srcds is 32-bit and os.clock() returns a 64 bit value on 64 bit systems. Around os.clock() time of 2140.xx, the decimal precsion increases and the negative bit gets set. So the values start counting at -2140.xxxxxx back toward 0. In order to solve this problem, we take the absolute differences in time values of the clock rather than just subtracting new - old. We ran a debuger overnight, which would log the clock time, last time, calculated play time, and final time (what gets logged to file) on a per-player basis and got this. At line 789, the clock time went negative but the actual playtime was preserved. Yeah there were a few seconds lost but I don't think it's significant enough for it to cause any issues.

Here's our patch, just save as sv_playerinfo.lua and put it in your ev_plugins folder (overwrite the existing). I also forked this Evolve port and committed the patch, here.
