Is there any lua function to get the time since given process is started?
Есть ли какая-нибудь функция lua для получения времени с момента запуска данного процесса?

--lua
local t = os.clock()

while true do
    log (os.clock() - t)
    wait (100)

Thanks for the fast reply, but that's not what I need.
Example:
I bind given script to 'calculator.exe', and I wanna know at what time 'calculator.exe' was started or for how long calcualtor.exe is running.
For what I need this? I just want to make script which checks if process is running for more than 3 hours.

note

-gt Greater than

Awesome! That's working, but is there any way to do it without using posh?
I just found this -> winapi/process.lua and now trying to implement it.

With posh you can solve almost all ur needs, without necessary to install any mods.
For example u can remember this issue.
Ask, if u'll need more help with the code.

Anyway, u can continue writing in lua below this luaposh block. Or above it.

Posh solution is very simple and clean! Just wanted to see ffi/winapi solution because I already had them imported in my script.
About this issue. Other problems popped up and sadly its not finished. :/

Works perfect! Thank you.
