nit: How about changing to a short constant as "divider".

You'll be comparing this string with each string, right?

[Alexander Alekseev, 2014/01/31 17:21:00]

Languages are all lower-case, so any string starting with capital letter is very
fast to compare. I've chosen a long one becase it is
self-descripting.
