+ # luatz
+ 
+ A lua library for time and date manipulation.
+ 
+ Features include:
+ 
+   - Normalisation of broken down date objects
+ 	  - allows for complex time/date manipulation logic e.g. "What day is it in 2 days, 5 hours from now?"
+   - Conversion between locations (time zones) using your local [zoneinfo](https://www.iana.org/time-zones) database.
+   - `strftime` style formatting
+ 
+ 
+ [![Build Status](https://travis-ci.org/daurnimator/luatz.png)](https://travis-ci.org/daurnimator/luatz) [![Coverage Status](https://coveralls.io/repos/github/daurnimator/luatz/badge.svg?branch=master)](https://coveralls.io/github/daurnimator/luatz?branch=master)
+ 
+ Supported under Lua 5.1, 5.2, 5.3 and LuaJIT.
+ 
+ 
+ ## Documentation
+ 
+ Documentation can be found in the `doc` sub-directory.
+ 
+ An online version can be found at https://daurnimator.github.io/luatz/

+ ## `luatz.gettime` <!-- --> {#gettime}
+ 
+ A module to get the current time.
+ 
+ Uses the most precise method available (in order:)
+ 
+   - Use [ljsyscall](http://www.myriabit.com/ljsyscall/) to access `clock_gettime(2)` called with `CLOCK_REALTIME`
+   - [lunix](http://25thandclement.com/~william/projects/lunix.html)'s `unix.clock_gettime()` (Only on non-Apple systems)
+   - Use [ljsyscall](http://www.myriabit.com/ljsyscall/) to access `gettimeofday(2)`
+   - [lunix](http://25thandclement.com/~william/projects/lunix.html)'s `unix.gettimeofday()`
+   - [luasocket](http://w3.impa.br/~diego/software/luasocket/)'s `socket.gettime`
+   - [Openresty](http://openresty.org/)'s [`ngx.now`](http://wiki.nginx.org/HttpLuaModule#ngx.now)
+   - [`os.time`](http://www.lua.org/manual/5.3/manual.html#pdf-os.time)
+ 
+ ### `source` <!-- --> {#gettime.source}
+ 
+ The library/function currently in use by [`gettime()`](#gettime.gettime).
+ 
+ 
+ ### `resolution` <!-- --> {#gettime.resolution}
+ 
+ The smallest time resolution (in seconds) available from [`gettime()`](#gettime.gettime).
+ 
+ 
+ ### `gettime()` <!-- --> {#gettime.gettime}
+ 
+ Returns the number of seconds since unix epoch (1970-01-01T00:00:00Z) as a lua number

+ ## `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

+ ## `luatz.timetable` <!-- --> {#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 facilitate 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]])` <!-- --> {#timetable.new}
+ 
+ Returns a new timetable with the given contents.
+ 
+ 
+ ### `new_from_timestamp(timestamp)` <!-- --> {#timetable.new_from_timestamp}
+ 
+ Returns a new (normalised) timetable, given a timestamp in seconds since the unix epoch of 
+ 1970-01-01.
+ 
+ 
+ ### `timetable:clone()` <!-- --> {#timetable:clone}
+ 
+ Returns a new independent instance of an existing timetable object.
+ 
+ 
+ ### `timetable:normalise()` <!-- --> {#timetable:normalise}
+ 
+ Mutates the current object's time and date components so that are integers within 'normal'
+ ranges e.g. `month` is `1`-`12`; `min` is `0`-`59`
+ 
+ First, fractional parts are propagated down.  
+ e.g. `.month=6.5` `.day=1` (which could be read as "the first day after the middle of June")
+ normalises to `.month=2` `.day=16`
+ 
+ Second, any fields outside of their normal ranges are propagated up  
+ e.g. `.hour=10` `.min=100` (100 minutes past 10am)
+ normalises to `.hour=11` `.min=40`
+ 
+ 
+ ### `timetable:rfc_3339()` <!-- --> {#timetable:rfc_3339}
+ 
+ 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, if you want a valid timestamp,
+ [`:normalise()`](#timetable:normalise) should be called first.
+ 
+ This function is also the `__tostring` metamethod for timetable objects
+ 
+ 
+ ### `timetable:timestamp()` <!-- --> {#timetable:timestamp}
+ 
+ Returns the timetable as the number of seconds since unix epoch (1970-01-01) as a lua number.
+ 
+ 
+ ### `timetable:unpack()` <!-- --> {#timetable:unpack}
+ 
+ Unpacks the timetable object; returns `year`, `month`, `day`, `hour`, `min`, `sec`, `yday`, `wday`

+ ## `luatz.tzinfo` <!-- --> {#tzinfo}
+ 
+ Provides a metatable for the timezone class.
+ 
+ Created in `luatz.tzfile` and managed by `luatz.tzcache`;
+ a timezone object contains information about a timezone.
+ These objects are based on the information available in a "zoneinfo" file.
+ 
+ Timezone objects should be considered opaque and immutable;
+ so the following details can be skipped over.
+ 
+ ------------------------------------------------------------------------------
+ 
+ The table contains a sequence of tables that describe the timezone at a given point
+ using a `transition_time`: the unix timestamp (in UTC) that this definition starts, and
+ a `tt_info` object.
+ 
+ A `tt_info` object contains information about a time offset;
+ and contains the following fields:
+ 
+   - `gmtoff` (number) The offset from GMT (UTC) in seconds
+   - `isdst` (boolean): If this change was declared as daylight savings
+   - `abbrind` (number, abbreviation id)
+   - `abbr` (string): short name for this gmt offset
+   - `isstd` (boolean)
+   - `isgmt` (boolean)
+ 
+ 
+ ### `tzinfo:find_current(utc_ts)` <!-- --> {#tzinfo:find_current}
+ 
+ Returns the relevant `tt_info` object for the given UTC timestamp in the timezone.
+ 
+ 
+ ### `tzinfo:localise(utc_ts)` and `tzinfo:localize(utc_ts)` <!-- --> {#tzinfo:localise}
+ 
+ Convert the given UTC timestamp to the timezone.
+ Returns the number of seconds since unix epoch in the given timezone.
+ 
+ 
+ ### `tzinfo:utctime(local_ts)` <!-- --> {#tzinfo:utctime}
+ 
+ Convert the given local timestamp (seconds since unix epoch in the time zone) to a UTC timestamp.
+ This may result in ambigous results, in which case multiple values are returned.
+ 
+ e.g. consider that when daylight savings rewinds your local clock from 3am to 2am there will be two 2:30ams.
