[Tracker] Date placeholders (translation)

[Matic Ågur <mr zgur gmail com>]

Hi,

I am translating Tracker to Slovenian and I would like to ask you a
question. There is a string, that is a bit confusing for me. It goes
like this: "%A, %B %-d %Y at %-I:%M:%S %p". The first part must be a
date and the other must be an hour. Translating an hour isn't a problem
(just replacing I with H and removing %p because we use 24 hour time).
However, I would like to ask you, what the other placeholders stand for.
I would imagine that %Y is year, but what about the others?

Thanks for your help and keep up a good work.

Cheers,
Matic Zgur
