I don’t see any obvious ways of making a new Date object based off of  
what Time.now rerurns. I’m ultimately trying to make a new Date from  
milliseconds:

tn = Time.now  
ms = ("%.6f" % tn.to\_f) #this would ultimately be comming from another  
source  
nd = Time.at( ms.to\_f / 1000.0 )  
puts nd.to\_a.inspect  
#d = Date.new(??)

The next step is making the date object. I don’t see anything obvious in  
the Date class. Any help?

Remember, ri is your friend™.

% ri Date::civil  
------------------------------------------------------------ Date::civil  
Date::civil(y=-4712, m=1, d=1, sg=ITALY)

require ‘date’

ms = 1173658884500.0  
nd = Time.at( ms.to\_f / 1000.0 )  
#puts nd  
#puts nd.to\_a.inspect  
f = nd.to\_a  
n = Date.parse("#{f[4]}-#{f[3]}-#{f[5]} #{f[1]}:#{f[2]}:#{f[3]}  
#{f[9]}")  
#puts n  
#puts n.class

correction: Date.parse("#{f[3]}-#{f[4]}-#{f[5]} #{f[1]}:#{f[2]}:#{f[3]}  
#{f[9]}")

Why the parsing?

irb(main):042:0\> t=Time.now  
=\> Mon Mar 12 19:59:33 +0100 2007  
irb(main):043:0\> d=Date.new(t.year, t.month, t.day)  
=\> #\<Date: 4908343/2,0,2299161\>  
irb(main):044:0\> d.strftime  
=\> “2007-03-12”

Kind regards

robert
