from this line, what if you're dissallowed to write Time.now? what if there is an existed time already, say : 1.week.ago . Do you have any ideas how to *get* that 1.week.ago.pst .... That's why I emphasized the output result should exist as a Time object instance instead of Time class method. from high level, one might say it answered my question, but from its code, I don't see it behaves as I want, it's not *get* an existed variable, it's (I mean, "it" means that line) was hacking itself to be a PST, or in another word, it still *sets* Time. > t.to_s # force localtime(3) call using this TZ > t > ensure > ENV['TZ'] = old_tz > end > end > end > > p Time.pst # Fri Mar 28 01:47:32 -0700 2008 > p Time.now # Fri Mar 28 15:47:32 +0700 2008 if it's all about setter I can just easily do this from a long time ago : >> Time.now => Fri Mar 28 17:29:10 +0800 2008 >> Time.zone.now => Fri, 28 Mar 2008 02:29:15 PDT -07:00 >> exit > rgds, > Edwin. -- blog: http://tinyurl.com/2bjgvn, ruby: http://www.ruby-lang.org/id/about I always thought Smalltalk would beat Java, I just didn't know it would be called 'Ruby' when it did. -- Kent Beck.
