+## `luatz`
+
+Requiring the base luatz module will give you a table of commonly used functions and submodules.
+
+The table includes the following sub modules, which have their own documentation:
+
+ - [`parse`](#parse): Parses common date/time formats
+ - [`timetable`](#timetable): Class for date/time objects supporting normalisation
+
+### `time()` <!-- --> {#luatz.time}
+
+Returns the current unix timestamp using the most precise source available.
+See [`gettime`](#gettime) for more information.
+
+
+### `now()` <!-- --> {#luatz.now}
+
+Returns the current time as a timetable object
+See `timetable` for more information
+
+
+### `get_tz([timezone_name])` <!-- --> {#luatz.get_tz}
+
+Returns a timezone object (see `tzinfo` documentation) for the given `timezone_name`.
+If `timezone_name` is `nil` then the local timezone is used.
+If `timezone_name` is an absolute path, then that `tzinfo` file is used
+
+This uses the local [zoneinfo database](https://www.iana.org/time-zones);
+names are usually of the form `Country/Largest_City` e.g. "America/New_York".
+Check [wikipedia](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) for an example list.
+
+
+### `time_in(timezone_name[, utc_ts])` <!-- --> {#luatz.time_in}
+
+Returns the current time in seconds since 1970-01-01 0:00:00 in the given timezone as a string,
+(same semantics as [`get_tz`](#luatz.get_tz)) at the given UTC time (defaults to now).
+
+
+### `gmtime(ts)` <!-- --> {#luatz.gmtime}
+
+As in the C standard library
+
+
+### `localtime(ts)` <!-- --> {#luatz.localtime}
+
+As in the C standard library
+
+
+### `ctime(ts)` <!-- --> {#luatz.ctime}
+
+As in the C standard library
