Objects for date/time

ColdFusion MX no longer strips milliseconds off of date/time objects; to do this, use the

date formatting functions.

Date pivot point for two-digit years

When ColdFusion processes a date that has does not include the century, ColdFusion

determines the century. To do this, ColdFusion compares the date to when it processes

the date. With a few exceptions, ColdFusion MX uses 20 as the date pivot point for

calculating the century in a two-digit year. ColdFusion 5 uses 29.

Note: The following locales use 28 as the date pivot point instead of 20:

English(Australian), English(New Zealand), German(Austrian), German(Standard), German

(Swiss), Portuguese(Brazilian), Portuguese(Standard), and Swedish. Macromedia has

confirmed this inconsistency using the SUN JRE version 1.4 and the IBM JRE version 1.3.0.

So in ColdFusion MX, if the date is within 80 years before and 20 years after the date

when it processes the date, then ColdFusion MX returns the date with the current

century. Otherwise, it returns the previous century. In ColdFusion 5, if the date is within

71 years before and 29 years after the date when it processes the date, then ColdFusion 5

returns the current century. Otherwise, it returns the previous century. This can cause

incompatible results. For example,

LSParseDateTime("25-12-13 22:10:15") returns a

year of 1925 in ColdFusion MX, and 2025 in ColdFusion 5.

Note: Results might differ, depending on your Java Runtime Environment (JRE). This

information reflects tests on the SUN JRE version 1.4 and the IBM JRE version 1.3.0.

Macromedia has also tested using the SUN JRE version 1.3.1_01; however, many of these

tests have failed on locales other than English(US).

class, at http://java.sun.com/j2se/1.3/docs/api/index.html.

Request variable

ColdFusion MX no longer supports the RequestTimeout attribute in the URL. For

pages expecting the

RequestTimeout attribute in the URL, add the following tag:

Reference.

Definition of pi

ColdFusion MX and ColdFusion 5 define pi with slightly different precision. Therefore,

you might obtain slightly different results between the two for trigonometric functions

such as sin, cos, and tan at the boundaries (0, 90, 180, 270, ... degrees).

Null values

ColdFusion 5 converted all null values to an empty string (“ ”). ColdFusion MX

preserves null values, but converts them to an empty string when you use them as simple

values.
