History

ColdFusion (2018 release): Introduced named parameters.

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).
