Copy commons-lang-2.3.jar to /temp:

set CLASSPATH=/temp/commons-lang-2.3.jar
\tools\jython2.2\jython.bat
>>> import java.util.Date
>>> d = java.util.Date()
>>> d2 = java.util.Date()
>>> import org.apache.commons.lang.time.DateUtils
>>> org.apache.commons.lang.time.DateUtils.isSameDay(d, d2)
1

…or, to make the code a little bit cleaner:

>>> from java.util import Date
>>> d = Date()
>>> d2 = Date()
1
>>> from org.apache.commons.lang.time import DateUtils
>>> DateUtils.isSameDay(d, d2)
1
>>> d2 = DateUtils.addDays(d2, 1)
>>> DateUtils.isSameDay(d, d2)
0
