History
ColdFusion MX:
•
Changed formatting behavior: this function might return a different result than in earlier
releases. This function uses Java standard locale formatting rules on all platforms.
•
Changed behavior: this function accepts a dash or hyphen character only in the
Dutch(Standard) and Portuguese (Standard) locales. If called this way (for example,
LsIsDate("3-1-2002") in any other locale, this function returns False. (Earlier releases returned
True.)
•
Changed behavior: when using the SUN JRE 1.3.1 on an English(UK) locale, this function
returns False for a date that has a one-digit month or day (for example, 1/1/01). To work
around this, insert a zero in a one-digit month or day (for example, 01/01/01).
