Time Format Conversions

elricstorm · August 31, 2009, 7:27pm

Hi all,

So, I’m trying to find out the best practice for converting a time
format from the following:

“3:00 PM”
“10:00 PM”
“1:00 AM”

TO:

“15:00:00”
“22:00:00”
“01:00:00”

Can anyone help me out on what I need to do here? I’m pulling strings
that need to be parsed and converted from > to the listings above.

Any help would be appreciated.

Many thanks in advance.

JD

gem install chronic

Chronic.parse(“3:00 PM”).strftime(’%H:%M:%S’)
=> “15:00:00”

Does this work?

Oops.

$ gem install chronic
$ irb

require ‘chronic’
Chronic.parse(“3:00 PM”).strftime(’%H:%M:%S’)
=> “15:00:00”

The standard library ‘time’ parses this too:

require ‘time’
puts Time.parse(“3:00 PM”).strftime(’%H:%M:%S’)
=> 15:00:00

hth,

Don’t need a gem, the ‘time’ package from the standard library will do:

require 'time'
new = Time.parse(old).strftime("%T")
