Time in W3C format

Question

How to make time in W3C format, including hours, minutes, seconds and time zone offset.

Example:

1997-07-16T19:20:30+01:00 

Update 1

I have the following declaration in config / locales / my_locale.yml:

 time: formats: w3c: %Y-%m-%dT%H:%M 

The only missing part is shifted, for example, "+01: 00". What is this interpolation symbol?

I found this link that contains the time zone name interpolated with% Z.

But where is the bias ?

Answer 1

To insert the offset time zone, use the% z (lowercase) key.

Answer 2

In fact, you should use%: z to include the + character. You also need to turn on the seconds.

 "%Y-%m-%dT%H:%M:%S%:z" 

Update: note that this is only possible with Ruby 1.9.3+, the%: z format marker is not available in earlier versions!

Answer 3

You already have an answer, but I just wanted to say that, since it does not depend on the user locale, but on the standard defined by the organization, it might be better to leave it outside the local file, for example en.yml

I personally add

 Time::DATE_FORMATS[:w3c] = "%Y-%m-%dT%H:%M:%S%:z" Date::DATE_FORMATS[:w3c] = "%Y-%m-%d"
