+"""
+http://yaml.org/type/timestamp.html specifies the regexp to use
+for datetime.date and datetime.datetime construction. Date is simple
+but datetime can have 'T' or 't' as well as 'Z' or a timezone offset (in
+hours and minutes). This information was originally used to create
+a UTC datetime and then discarded
+
+examples from the above:
+
+canonical:        2001-12-15T02:59:43.1Z
+valid iso8601:    2001-12-14t21:59:43.10-05:00
+space separated:  2001-12-14 21:59:43.10 -5
+no time zone (Z): 2001-12-15 2:59:43.10
+date (00:00:00Z): 2002-12-14
+
+Please note that a fraction can only be included if not equal to 0
