DEVELOPING COLDFUSION 9 APPLICATIONS 44 The CFML Programming Language When you do this, ColdFusion stores the information as a string. If you use a date-time function, ColdFusion stores the value as a date-time object, which is a separate simple data type. When possible, use date-time functions such as CreateDate and CreateTime to specify dates and times, because these functions can prevent you from specifying the date or time in an invalid format and they create a date-time object immediately. Date and time formats You can directly enter a date, time, or date and time, using standard U.S. date formats. ColdFusion processes the twodigit-year values 0 to 29 as twenty-first century dates; it processes the two-digit-year values 30 to 99 as twentieth century dates. Time values can include units down to seconds. The following table lists valid date and time formats: To specify Date Time Date and Time Use these formats October 30, 2003 Oct 30, 2003 Oct. 30, 2003 10/30/03 2003-10-30 10-30-2003 02:34:12 2:34a 2:34am 02:34am 2am Any combination of valid date and time formats, such as these: October 30, 2003 02:34:12 Oct 30, 2003 2:34a Oct. 30, 2001 2:34am 10/30/03 02:34am 2003-10-30 2am 10-30-2003 2am Locale-specific dates and times ColdFusion provides several functions that let you input and output dates and times (and numbers and currency values) in formats that are specific to the current locale. A locale identifies a language and locality, such as English (US) or French (Swiss). Use these functions to input or output dates and times in formats other than the U.S. standard formats. (Use the SetLocale function to specify the locale.) The following example shows how to do this: #LSDateFormat(Now(), "ddd, dd mmmm, yyyy")# This example outputs a line like the following: mar., 03 juin, 2003 For more information on international functions, see "Developing Globalized Applications" on page 364 and the CFML Reference.
