Subject: [ruby-core:21473] Time.gm give me ArgumentError out of range (ruby 1.8.6 (2007-09-24	patchlevel 111) [i486-linux])

Hi all,
today i was fetching some data from a database through odbc and during
mapping of types i got argument error 'out of range'.
To repeat this error i have created a new file, very simple, with this:

puts Time.gm(2009,1,1)
puts Time.gm(1800,1,1)

and this is the result:

prova.rb:2:in `gm': time out of range (ArgumentError)
	from prova.rb:2

I found out that the first year that doesn't return error is 1902.
Digging in file time.c i read about the tmcmp function, but i couldn't
understand why, can someone explain me please?

Thanks a lot

Claudio
