comment How can this AbsoluteTime call be made faster?
Ahh sorry, my fault. Unfortunately the same approach in the other direction is not faster than your solution. Perhaps somebody else knows how to speed things up in this case.

comment How can this AbsoluteTime call be made faster?
Did you try to evaluate this function? Something like f[x_Integer] := Evaluate[DateString[ x, {"Year", "-", "Month", "-", "Day", " ", "Hour", ":", "Minute", ":", "Second"}]]; and f /@ Range[3576302100 - 10000, 3576302100]? For me this is about 4 times faster. But there is a hint that x can not be interpreted as a date or time input. Perhaps there is a way to define f in a way that this warning does not occur.

@IstvánZachar You're right. Thanks for the correction. I just copied the output of the formated cell using CMD + Shift + E.
