Hi
i need to compare zulu date and with current date

example :
expire_date=20130505172938Z

now i need compare that date with current time example

current_time= Time.now.strftime( "%y%m%d%H%M%S" )

now if current_time is 3 days behind then expire_date then do something
... ....

but the problem is :
i cant convert zulu time into current time ..

Any help will be really appreciate .

probably easier to do the opposite and convert the current time to Zulu
time.

expire_date = Date.parse("20130505172938Z")
current_time = Time.now.utc

then do something with them

def days_away(from, to)
  ((to - from) / (60 * 60 * 24)).ceil
end

if days_away(current_time, expire_date) == 3
  do_stuff
end

Hi Thanks
i am doing this

#!/usr/bin/ruby
require 'rubygems'
require 'time'
expire_date = Date.parse("20130505172938Z")
current_time = Time.now.utc

#puts expire_date
#puts current_time

def days_away(from, to)
  ((to - from) / (60 * 60 * 24)).ceil
end

if days_away(current_time, expire_date) == 3
  puts "test"
end

but it giving me

/usr/lib/ruby/1.8/date.rb:1220:in `-': expected numeric or date
(TypeError)
  from test.rb:11:in `days_away'
  from test.rb:14

i tryed with .to_datetime but no luck
what is i am missing???

Sorry I should have typed

Time.parse("20130505172938Z")

not

Date.parse("20130505172938Z")
