New Revision: 271

Modified:
   branches/owd/rnc/nmtime.rnc
Log:
Enumerating valid time 'types' in the rnc. (Also put some text to specify
the valid values given those types in comments. The information from
the comments is perhaps a reasonable start at some protocol documentation
for time specifics.)

+# Time types are enumerated as follows:
+#
+# * unix: integral seconds since Jan 1, 1970 (UTC)
+#
+# * iso9601/rfc3339:
+#
+#       full date/time representation. Examples from RFC-339:
+#
+#        Here are some examples of Internet date/time format.
+#     
+#           1985-04-12T23:20:50.52Z
+#     
+#        This represents 20 minutes and 50.52 seconds after the 23rd hour of
+#        April 12th, 1985 in UTC.
+#     
+#           1996-12-19T16:39:57-08:00
+#     
+#        This represents 39 minutes and 57 seconds after the 16th hour of
+#        December 19th, 1996 with an offset of -08:00 from UTC (Pacific
+#        Standard Time).  Note that this is equivalent to 
1996-12-20T00:39:57Z
+#        in UTC.
+#     
+#           1990-12-31T23:59:60Z
+#     
+#        This represents the leap second inserted at the end of 1990.
+#     
+#           1990-12-31T15:59:60-08:00
+#     
+#        This represents the same leap second in Pacific Standard Time, 8
+#        hours behind UTC.
+#     
+#           1937-01-01T12:00:27.87+00:20
+#     
+#        This represents the same instant of time as noon, January 1, 1937,
+#        Netherlands time.  Standard time in the Netherlands was exactly 19
+#        minutes and 32.13 seconds ahead of UTC by law from 1909-05-01 
through
+#        1937-06-30.  This time zone cannot be represented exactly using the
+#        HH:MM format, and this timestamp uses the closest representable UTC
+#        offset.
