Hmm... I don't know. Should this work? I admit to being confused here. $ date -u -d '2015-06-30 23:59:60 UTC' date: invalid date ‘2015-06-30 23:59:60 UTC’
$ date -R -d '2015-06-30 23:59:59 UTC + 1 second' Tue, 30 Jun 2015 18:00:00 -0600 I guess we have a little over three hours to find out! :-) Bob
