LSIsDate(string [, locale])
CreateDateTime, GetLocale, IsNumericDate, LSDateFormat, ParseDateTime, SetLocale; Handling data in ColdFusion in the Developing ColdFusion Applications
ColdFusion 8: Added the locale parameter.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).
