That would be really handy.  I've been fiddling a bit more the past couple of days, and I can't quite get it to work properly.  I don't know if the failure is in the class file, the jar, or loading it in the test.rb

I chose unix_timestamp because that's what MySQL calls it (UNIX_TIMESTAMP and FROM_UNIXTIME), and a quick and very scientific Google poll shows me that "unix timestamp" has ~893k results, "epoch timestamp" ~463k, "posix timestamp" ~430k; and the second, third, and fifth results for "timestamp" are www.unixtimestamp.com/, www.epochconverter.com/ (the "Easy epoch/Unix timestamp converter for computer programmers.") and www.onlineconversion.com/unix_time.htm, etc. so the "Unix" name is in pretty common usage.

Feature #8096: introduce Time.current_timestamp

A lot of scenarios and applications require the use of (({Time.now.to_i})) which is used as current_timestamp in systems.

The introduction of (({Time.current_timestamp})) {or something with similar with different name} would provide implicit integer timestamp instead of going from 
(({Time.now})) -> time_object -> to_i -> integer timestamp value

So instead of

 Time.now.to_i # Outputs => 1363274618

one could use

 Time.current_timestamp # Outputs => 1363274618
