MyDNN.org released a new version of MyDNN TimeZones Pro on Feburary 28th, 2007.  The new release adds functionality for time zones which do not fall on an hour boundary (like India's +5:30 or Australia's +8:45) and Australia's Lord Howe Island (DST +0:30)).  The version 1.2 release also includes numerous bug fixes and small enhancements.

Be aware of the change in when the US moves to Daylight Saving Time.  Congress changed the date to March 11th through November 4th for 2007 (Energy Policy Act of 2005).  Both version 1.1.2 and 1.2.0 (newly released) recognize this change in the date.
