The type of the fromdate or todate in several methods is set to
unix epoch date, range [0, 253,402,300,799]
I don't know what that is and I can't find any information -- can someone explain it or point me to the right place?

These are Unix timestamps. They represent the number of seconds that have passed since the Unix Epoch, which occurred at 12:00 am UTC on January 1, 1970.
You can convert a human-readable date to / from a Unix timestamp using Wolfram Alpha. Example queries:
"convert January 15, 2005 14:56 PST to unix timestamp"
"convert unix timestamp 1105829760"
The end of the range is the highest possible date represented by as a timestamp.

1Thank you for your answer. What I don't understand is the
range [0, 253,402,300,799]part. And the wikipedia article doesn't seem to say something about it..phi– phi2011-12-09 09:56:47 +00:00Commented Dec 9, 2011 at 9:56 -

I honestly don't know what that number represents. My best guess is that it represents the maximum value returned in that field.Nathan Osman– Nathan Osman2012-02-05 20:25:51 +00:00Commented Feb 5, 2012 at 20:25
