API: history.get and keep history limit

[r-br]

I use the history.get API method to retrieve data from the database. Everything is fine. But I have an item which has "keep history" set to 60 days, and it seems that the history.get API won't retrieve data before 60 days... am I correct?

Then, how could I retrieve such data?...

On the API (version 1.8.3), I need to retrieve some history data through history.get, something like this:

{
  'history'   : 3,
  'itemids'   : [ 32755, 32749 ],
  'time_from' : 1299233040,
  'time_till' : 1299236640,
  'output'    : 'extend'
