Don't forget the interval between 1365867000 and 1365867005 which is also
part of this minute. It's the minute from 1365867000 to 1365867060. 22
ticks in 60 seconds should result in 0.3666... 0.36438774029 is not
correct but it is close. I suspect there are rounding errors involved.
Tobi, could you shed some light on this?
