H1B+L1B combined stay duration

[Vivek158]

Please advise what is the total duration one can stay (5 or 6) with current L1B visa. I had H1b in the past and stayed in US for 2 yrs. I went back to India as my H1b extension got rejected. I got another L1b and entered US ( total 2 yrs stay again). Not sure total duration left in my current visa. I was out for more than year during my L1 active visa status and not between h1 and l1.

I am not sure if clock will get reset in this case?
Please advise how much I can stay further in my current L1b visa?
