Overview
The DT, or date and time plugin, is an ExpressionEngine plugin that displays dates with formatting you set and allows you to add or substract days, months, years, hours, minutes and seconds to the current date/time or a static date you set.
It's as easy as setting the tag with the following parameters {exp:dt day=“3” month=“1” year=”-1” set=“1/1/2010”} to return something like this: 02/04/09. DT is helpful anytime you need to return a modified date inside of an ExpressionEngine template.
