When does it add an hour? Is it only on specific input strings, or is
it arbitrary? If its the former, what input strings does it happen
on? Can you spot any pattern to the inputs that it occurs on?
It's possible that it's getting confused with dates either side of the
British Summertime change.
Also, your variable names are rather cryptic... you might consider
using studlyCapsWithCapitalInitialLetters or
underscores_between_words.
