http://issues.apache.org/bugzilla/show_bug.cgi?id=25560 DateUtils.truncate() is off by one hour when using a date in DST switch 'zone' [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |FIXED ------- Additional Comments From [EMAIL PROTECTED] 2004-07-11 17:04 ------- The truncate/round logic was adding a negative value to the current hours (using Calendar.add) to move the hours back to zero. When this is done across the beginning of daylight saving time, it has the affect of moving to 23:00 of the previous day, because the hour skipped when daylight saving time doesn't exist. For example, if daylight saving time begins at 02:00, and -5 is added to 05:00, the result is 23:00 of yesterday, because the hour between 02:00 and 03:00 doesn't exist. The fix was to do the calculation in the truncate/round code, and use Calendar.set to set the new hour value. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
