Hi,

I would like to get a timestamp from a Date object. What is the best
aproach for this?

thank you

I think you want a DateTime or Time object, I believe a Date object only represents a date, not a date and
time unless perhaps 'date at midnight' counts.

I'm not sure if this is the most effective, but

d = Date.new(2009, 11, 18)
ts = d.strftime('%s').to_i

seems to work for me, giving the timestamp for 2009-11-10 00:00:00 GMT

Hope this helps,

Mike

Don't know if this is what you're looking for but whenever I need a
serial-style timestamp (like for a filename). I just do this:

Time.now.strftime("%Y%m%d%H%M%S")

Hi,

It's enough to have the milliseconds since a given date in the past,
for example java has this:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Date.html#getTime()

It's there anything comparable in Ruby?

Thanks

Hint: there is documentation...

irb(main):001:0> Time.now.to_i
=3D> 1258647502
irb(main):002:0> Time.at(0)
=3D> 1970-01-01 01:00:00 +0100
irb(main):003:0> Time.at(0).to_i
=3D> 0

Cheers
