Brigado Mauricio for the replay, yep,
this was on scraped data, ashamed to say that I wasn't checking its
integrity,
when i got the data like this: yyyy-mm-ddhh_mm (without space between
dd and hh),
interestingly enough, after 2,200 parses the parser starts the 2 hour
drift,
(I am making sure that the date string comes properly formatted now)
but still, an interesting 'feature'
