LS Formatting works differently from CF 5 to CF MX
MX uses Java locale standards in its locale specific functions
Previous versions of ColdFusion used either Windows or Unix locale-specific rules depending on the platform.
By using Java standards, consistency is achieved across all platforms. However, this means that lsParseDateTime will now produce slightly different results than previous versions.
