If you do specify which second as in Time += Base(2005-12-31-23:59:59-UTC) + 00:00:002 Does the library produce the proper result?

Happy New Year! Philip WAIT A SEC FOR LEAP INTO 2006 Get ready for a minute with 61 seconds. Scientists are delaying the start of 2006 by the first "leap second" in seven years, a timing tweak meant to make up for changes in the Earth's rotation.... ... http://www.cnn.com/2005/US/12/25/leap.second.reut/index.html ------------------------------------- You are subscribed as BobIP () Bobf Frankston com To manage your subscription, go to http://v2.listbox.com/member/?listname=ipArchives at: http://www.interesting-people.org/archives/interesting- people/
