AC500

A simple Java libary for retrieving time information from the Galleon AC500 atomic clock receiver.

It will generally return the correct time to the nearest second or so, but is not hugely accurate beyond this point since it does not (at present) account for the transmit time. PR's to take the exact transmit time into account are welcome - it should be reasonably easy to calculate from the baud rate.

Use at your peril - this is nothing more than a thrown together proof of concept at present :-)

JSSC is required as a dependency for the serial communication.

Setup

Maven

<dependency>
  <groupId>com.github.berry120.ac500</groupId>
  <artifactId>ac500</artifactId>
  <version>1.0</version>
</dependency>

Gradle

compile 'com.github.berry120.ac500:ac500:1.0'

Example usage:

AC500 ac500 = new AC500("COM2");                              //Change to whatever port the AC500 is attached to.
ZonedDateTime ldt = ac500.getTime().asZonedDateTime();        //Get current time as the Java 8 LocalDateTime object
DateTimeFormatter dtf = DateTimeFormatter.RFC_1123_DATE_TIME;
System.out.println(dtf.format(ldt));                          //eg. Wed, 7 Jan 2015 17:30:13 GMT
