+# `luatz.gettime`
+
+A module to get the current time.

+
+## `gettime`
+
+Uses the most accurate method available (in order:)
+
+  - Uses luasocket's `socket.gettime` if available
+  - `os.time`

+# `luatz.parse`
+
+Provides parsers for common time and date formats.
+
+Functions take the source string and an optional postition.
+
+## `rfc_3339`
+
+Returns a luatz timetable and the (optional) time zone offset in seconds

+# `luatz.timetable`
+
+Provides an class to represent a time and date.
+Objects have no concept of timezone or utc offset.
+
+The fields are intentionally compatible with the lua standard library's `os.date` and `os.time`. Objects have fields:
+
+  - `year`
+  - `month`
+  - `day`
+  - `hour`
+  - `min`
+  - `sec`
+  - `yday` (optional)
+  - `wday` (optional)
+  
+timetable components may be outside of their standard range (e.g. a month component of 
+14) to faciliate arithmetic operations on date components. `:normalise ( )` can be 
+called to modify components to return to their standard range.
+
+Equality and comparisons should work between timetable objects.
+
+
+## `new ( year , month , day , hour , min , sec , [yday] , [wday] )`
+
+Returns a new timetable with the given contents.
+
+
+## `new_from_timestamp ( timestamp )`
+
+Returns a new timetable given a timestamp in seconds since the unix epoch of 
+1970-01-01.
+
+`:normalise ( )` should probably be called before use to resolve to the current time and 
+date.
+
+
+## `:clone ( )`
+
+Returns a new independant instance of an existing timetable object.
+
+
+## `:normalise ( )`
+
+Mutates the current object's time and date components so that they lie within 'normal' 
+ranges e.g. `month` is `1`-`12`; `min` is `0`-`59`
+
+
+## `:rfc_3339 ( )` and `__tostring` metamethod
+
+Returns the timetable formatted as an rfc-3339 style string.
+The timezone offset (or Z) is not appended.
+The ranges of components are not checked, and if you want a valid timestamp, `:normalise 
+( )` should be called first.
+
+
+## `:timestamp ( )`
+
+Returns the timetable as the number of seconds since unix epoch (1970-01-01) as a lua 
+number.
