Hello,

When i have a Time object, to get to next day i do: myTime += (60*60*24)
Not very elegant, but it works and I didn't find a nicer way.
well, i thought it worked...

now we are going to change the time in europe...
So it breaks my assumption...

any proper way to fix it?

irb(main):008:0> now = Time.now
Tue Oct 21 08:14:44 Central Europe Daylight Time 2003
irb(main):009:0> todayMidnight = Time.local(now.year, now.month,
now.day, 0,0,0)
Tue Oct 21 00:00:00 Central Europe Daylight Time 2003 # today at 0:00

irb(main):010:0> todayMidnight + (60*60*24)
Wed Oct 22 00:00:00 Central Europe Daylight Time 2003 # tomorrow at 0:00

[..]

irb(main):014:0> todayMidnight + (60*60*24)*5
Sun Oct 26 00:00:00 Central Europe Daylight Time 2003 # sun at 0:00
irb(main):015:0> todayMidnight + (60*60*24)*6
Sun Oct 26 23:00:00 Central Europe Standard Time 2003 # <----------
!!!! sun at 23:00

If you just want dates, what about date.rb?

require 'date'
today = Date.today
today.to_s # => "2003-10-21"
(today+5).to_s # => "2003-10-26"

I've not tested it with DST though.

find.rb, base64.rb, date.rb, the other day someone wanted to remove
recursively a dir, and was given another one of those magic files...
which doc did i miss? :O(

otherwise, yes it's probably what i want. unfortunately i now sit on a
lot of code to convert :O(
if someone has a way with Time, it would simplify things for me...

thanks,

emmanuel

Here's half a solution:

class Time
require 'date'
DAY = 60*60*24

alias add +
def +(s)
return add(s) unless s % DAY == 0
d = Date.new(year, mon, day) + s / DAY
Time.local(d.year, d.mon, d.day, hour, min, sec, usec)
end
end

some is in the pickaxe.
Some you may just found looking at ruby-dir/lib, for the classes like
Array or String there is ri.

You may like to look at rj (as in 'ri'.succ) wich works like ri but
incorporates some more stuff (see on rubyforge).

ruby-doc.org has ri++ wich is 'ri + documentation via web' . Quite
useful too
