Description: # `time_converter` [![build status](https://gitlab.physik.uni-kiel.de/ET/time_converter/badges/master/build.svg)](https://gitlab.physik.uni-kiel.de/ET/time_converter/commits/master) [![coverage report](https://gitlab.physik.uni-kiel.de/ET/time_converter/badges/master/coverage.svg)](http://et.page.physik.uni-kiel.de/time_converter/coverage/)
        
        A Python class that allows for convenient conversion between different date and time formats and units.
        The library supports both general-purpose Earth-based time units (such as Python's `datetime` type, Day-of-year or
        POSIX time) as well as time units useful for working with data from the Mars Science Laboratory and Chang'e 4 space
        missions. It can be easily extended to support additional units.
        
        ## Installation
        ```python
        pip3 install time_converter
        ```
        
        Yes, it's that simple.
        
        ## Usage
        ```python
        from time_converter import Time
        
        Time(2019.5, 'decimalyear').to('dt')
        # > datetime.datetime(2019, 7, 2, 12, 0)
        ```
        
        you can also supply list-like objects as input, the output will be a `numpy` array.
        ```python
        Time([2018.0, 2018.1], 'decimalyear').to('dt')
        # > array([datetime.datetime(2019, 1, 1, 0, 0),
        #          datetime.datetime(2019, 2, 6, 11, 59, 59, 999997)], dtype=object)
        ```
        
        ## Supported units
        
        ### Earth-based time units
        
        | Unit                          | Example                               | Name          | Abbreviated Name |
        |-------------------------------|---------------------------------------|---------------|------------------|
        | Python datetime (UTC)         | `datetime.datetime(2019, 1, 1, 0, 0)` | `datetime`    | `dt`             |
        | DoY Tuple (year, day of year) | `(2019, 1.0)`                         | `doy`         |                  |
        | Decimal year                  | `2019.0`                              | `decimalyear` | `dy`             |
        | POSIX time                    | `1546300800`                          | `posix`       |                  |
        
        ### Mars Science Laboratory
        
        The MSL spacecraft clock (`sclk`) measures the number of seconds since January 1 2000, 11:58:55.816 UTC. However, due to
        drifting of the clock, some corrections need to be applied based on
        [files supplied by NASA](https://naif.jpl.nasa.gov/pub/naif/pds/data/msl-m-spice-6-v1.0/mslsp_1000/data/sclk/sclkinfo.txt),
        which this tool uses to do the conversion between `sclk` and other units.
        
        | Unit                 | Example              | Name   |
        |----------------------|----------------------|--------|
        | MSL mission sol      | `2276.8306983767375` | `sol`  |
        | MSL spacecraft clock | `599570768.5720837`  | `sclk` |
        
        ### Chang'E 4
        
        For Chang'E 4, the conversion of spacecraft clock time to datetime has already implemented, so it does not need to be
        included in time_converter. But we have implemented a converter for the lunar day number and local solar time at
        Chang'E 4's landing site:
        
        | Unit                           | Example                       | Name       |
        |--------------------------------|-------------------------------|------------|
        | Local solar time at Chang'E 4  | `1, datetime.time(7, 32, 30)` | `ce4lst`   |
