+the json module was added with python2.6, so a regular python 2.5
+machine will lack this module and won't probably have the simplejson
+module imported by the leapsecond.py script.
+
+Since the only function used is the isotime function, which is
+self-contained and quite trivial, only copy this function into the
+leapsecond script to avoid the import of the gps.misc module, which
+needs simplejson.
