IROX-TIME
==========

A date & time library that aims for ease of use using static compile-time types based on the Proleptic Gregorian Calendar. 

Goals:
  * Provide type-safe, correct, easy conversions between [`Epoch`s]https://en.wikipedia.org/wiki/Epoch
  * Provide type-safe, correct, easy conversions between the [Unix Epoch]https://en.wikipedia.org/wiki/Unix_time and 
      the associated [Gregorian Date] and [Time]

Non-goals:
  * Handle strange edge cases like:
    * [Old Style Dates]https://en.wikipedia.org/wiki/Old_Style_and_New_Style_dates and the 
        [various 10-14 days that don't exist.]https://en.wikipedia.org/wiki/List_of_adoption_dates_of_the_Gregorian_calendar_by_country#List
    * [Year Zero]https://en.wikipedia.org/wiki/Year_zero
    * [Julian Leap Year Error]https://en.wikipedia.org/wiki/Julian_calendar#Leap_year_error
  * Handle Time Zones and Daylight Savings Time

Eventually:
  * Leap Seconds and UTC Proper

Module Structure
------------------
* [`time`]src/mod.rs - Contains the base `Time` struct, describing a standard `Hours/minutes/seconds` framework.
* [`datetime`]src/datetime.rs - Contains `UTCDateTime` structs, describing a `Date` with a `Time`
* [`epoch`]src/epoch.rs - Contains `Epoch`, `UnixEpoch`, `GPSEpoch`, and others, providing the datum anchor for timestamps 
    `UnixTimestamp`, `GPSTimestamp`, etc.
* [`format`]src/format/ - Date & Time Formatters & Parsers
  * [`iso8601`]src/format/iso8601.rs - ISO8601 Date Formats
  * [`rfc3339`]src/format/rfc3339.rs - RFC3339 Date Formats, a slight variation on ISO8601
* [`gregorian`]src/gregorian.rs - Contains `Date` and `Month`, that describe a gregorian calendar date.

Features
---------
* `std` - adds 'std' support:
  * `UnixTimestamp::now() -> UnixTimestamp`
  * `UnixTimestamp::elapsed() -> Duration`
  * `UTCDateTime::now() ->UTCDateTime`
  * impls of `std::error::Error` on errors
