“Time is stored internally as the number of seconds with fraction since the Epoch, January 1, 1970 00:00 UTC.”
>>require 'time' >>Time.parse("January 1, 1970 00:00 UTC").to_i => 0
As expected, but nice to verify.
For the reverse, be sure to use Time.at rather than Time.new
>> Time.at(0).to_i => 0 >> Time.new(0).to_i => -62167201200
