Date conversion strange behaviour

[simplsol at aol.com]

Herve,
I'm sorry I've taken so long to reply. I saw your post yesterday 
morning but have been very busy.
Anyway, I'm sure everyone will get the same results you did with the 
date conversion.
The problem is in OS X, not Revolution. In OS X days that go onto 
daylight savings time (summer time, war time, etc.) have 23 hours; 
those that come off dst have 25. The seconds calculations work fine - 
unless they cross a 23 or 25 hour day.
We had a long discussion on this subject about a year ago here on the 
list and in a special group of especially interested users. We 
recommended a way for Rev. to handle this but, so as I know, nothing 
has been done about it.

Subject: Date conversion strange behaviour

   Hi, 
 
  Can someone verify the result of this little script on both platform 
Win and MacOS : 
 
 on mouseUp 
   put "01/01/06" into d0 
   put "04/12/06" into d1 
   convert d0 to seconds 
   convert d1 to seconds 
   answer d0,d1,d1-d0,(d1-d0) div 86400 
 end mouseUp 
 
 On MacOS the result is: 1136073600,1144800000,8726400,101 
 On Win: 1136077200,1144800000,8722800,100 
 
  The difference between the two platform is 1 hour for d0 only, and the 
resulting difference between d0 and d1 is 101 days on MacOSX and 100 
days on Win ! 
 
 Any idea ?
