Welcome to the forums.
Lots of people have had this problem, and I'm not sure of the reasons why, but these are the usual suggestions people give for this problem

Try turning all the in-game options to their lowest values, and see if that helps.
Also be aware that switching to other pages while in game will slow your timer, but the server timer continues at normal speed.
Running other programs at the same time can also slow your computer, and make this problem worse

Is it the latest version of supermechs you're playing (should say 'ver 2.5B in the bottom right of the loading screen)?
Have you tried playing it from the official site?

--If none of that helps--

Is your computer relatively fast, browser and flash up to date etc.?

How is your internet speed?
[check your speed against a server in Texas, as apparently that's where the Supermechs server is].

I have done all the stuff you have mentioned above .... and also tried different browsers... as well as reported it to the bug report form 2 times (without reply)

and still i keep losing the time and it is multiple times in one each match ... this is getting very frustrating .. as on average every 2 or 3 PvPs I am losing 1 or 2 complete turns ... the most has been 4 complete turns my bot stood there like a moron just letting the other guy pound me ...
