Time.strftime and UTC

ruby-talk
1

Hi, just wondering if I'm missing something...

mcl@saluki:~$ ruby -v
ruby 1.8.2 (2004-11-06) [i686-linux]
mcl@saluki:~$ ruby -e 'puts Time.new.utc.strftime("%H:%M %Z")'
04:31 GMT

If I say to convert to UTC, shouldn't I get %Z = "UTC"?

It also contradicts page 649 of Pickaxe2 which says that 1.8+
would have UTC instead of GMT anyway.

Thanks.

Hi,

04:31 GMT

Unlike inspect or to_s, strftime honors underlying strftime(3)
function on the platform. This means strftime(3) function on your
platform returns GMT for %Z for time on UTC zone. I'm not sure this
situation could be fixed, since it requires either

  * abandon strftime(3) and re-implement the whole time formatting
    function.

  * or seek for the format string and replace %Z to UTC if a time is
    in the UTC zone.

which cost us much anyway.
