to_i_timestamp returns the computed UTC timestamp regardless of the timezone.

2011-01-01 00:00:00 UTC  ===> 14975
2011-01-01 23:59:59 UTC  ===> 14975
2011-01-02 00:00:00 UTC  ===> 14976

to_i_hour returns the hour for the date, again regardless of TZ

2011-01-01 00:00:00 UTC  ===> 0
2011-01-01 23:59:59 UTC  ===> 23
