ParseDate.parsedate() and Time.now

Patrick Spence

8/11/2006 4:11:00 PM

irb(main):029:0> timeNow = Time.now().to_s()
=> "Fri Aug 11 11:03:36 Central Daylight Time 2006"

irb(main):030:0> ParseDate.parsedate(timeNow)
=> [nil, 8, 11, 11, 3, 36, "Central", 5]

Seems to me that it should return this:
=> [2006, 8, 11, 11, 3, 36, "Central", 5]

Or is it just me?

It's you. Specifically, something's wrong with your locale, because
"Central Daylight Time" should actually be replaced with the abbreviation
"CDT".

irb(main):001:0> timeNow = Time.now().to_s()
=> "Fri Aug 11 13:49:07 CDT 2006"
irb(main):002:0> ParseDate.parsedate(timeNow)
=> [2006, 8, 11, 13, 49, 7, "CDT", 5]

The point I was trying to make is that the 1st element of the array
returned by parsedate() seems that it should contain the year 2006,
intstead of a nil.

As for the issue of returning "Central" vs "CST" or "CDT", I'm not
overly concerned with that at this time. No doubt, that will change.

I'm not sure it'll change. You're on Windows, and Windows is stupid
this way, preferring to spell out "Central Daylight Time" instead of
"CDT"; I have yet to figure out how to get the output from a Windows
format string to be abbreviated or better yet to return a +/- offset.

It is the "Central Daylight Time" that is causing the parsing to be
incorrect, because most date systems are sensible.

It may be worth reporting a bug to the tracker on RubyForge.org. If
you can figure out a patch, that's even better and you can also put it
in the same place.

It's time to make use of missing/strftime.c when on Windows.
