I am not a phoney Dutch nevermind a real one.  ;-)

  MK>> 'YYYY-MM-DD HH:MM:SS(+|-)HHMM' to be the ideal format

 WvV> Me too!

Using coreutils' date command with the --rfc-3339=seconds switch produces;

  2015-06-05 18:25:48+00:00

I forgot the ':' character in the utc offset between hours and seconds in the
MK>> quote above although I believe it isn't required.

Life is good,
Maurice
