islastmodified

+ +

Tests the last modified date of a resource. Since Ant +1.8.0

+ + + + + + + + + + + + + + + + + + + + + + + + + +
AttributeDescriptionRequired
millisSpecifies the expected modification time of the resource + in milliseconds since midnight Jan 1 1970.Exactly one of the + two.
datetimeSpecifies the expected modification time of the + resource. The special value "now" indicates the + current time.
patternSimpleDateFormat-compatible pattern string. + Defaults to MM/DD/YYYY HH:MM AM_or_PM or MM/DD/YYYY HH:MM:SS AM_or_PM. + No
modeHow to compare the timestamp. Accepted values + are "equals", "before", "not-before", "after" and "not-after". + No, defaults to "equals".
+ +

The actual resource to test is specified as a nested element.

+ +

+ An example: +

+
+<islastmodified dateTime="08/18/2009 04:41:19 AM" mode="not-before">
+  <file file="${file}"/>
+</islastmodified>
