29th instead of 27th? Sorry I cannot explain that one. If you had said 9 days after the 27th then I could have guessed that leap years were not being taken into account, but a difference of exactly 2 days does not make any sense to me.

The conversion I did was

TS = 1162160236000; datestr(datevec(TS/60/60/24/1000) + [1970 0 0 0 0 0])

The 1970 is in accordance with the Unix time convention of using time since the beginning of 1970.

If the difference had been 12 to 13 days, it could have represented an adjustment for the years ending in 00 not being leap years unless they were also divisible by 400. But 2 days off, I am at a loss for.

Why do you believe this is a timestamp?

Is that a string or an integer? How does the number break down into hours, minutes, and seconds?
