Tinfo
From ASSS Wiki
*tinfo is a Subgame command that shows you a short history of a user's timestamps. These timestamps are values in which both the server and the user's client returns for a tick value. Everything dealing with the client's physics is calculated based upon these values. Thus, if a user's clock is running faster or slower than the server's clock, this will cause the client to see things that no one else does, such as weapons missing ships or ships recharging or moving too fast.
Some possible causes for a fast system clock is a user maybe running a program specifically designed to speed up or slow down the system clock. This is know as 'speed hacking'. Another cause could be some random software error that can cause it, such as a java bug or weird virtual memory bugs.
A way to check if a user's clock is running fast is to look at the user's *tinfo result. Below as two sample tinfo returns, the first one in which a user's clock is running too fast while the second one is working perfectly. Notice how the Diff values are slowly decreasing in the bad tinfo, while in the good one they remain about constant. This is what you look for. Calculating the variance of these Diff values results in the good one having a variance of 0.5 with the bad one having a variance of 247,926 which is slightly noticable.
