Glue - Clock

Easy way of adding a clock to your Glue ecosystem.

Usage

The clock will broadcast the messages listed below, with a maximum delay of 166ms at most, plus bus latency. You can expect no more than 200-250ms on a decent network. The payload of the message is always the timestamp in milliseconds, as returned by the Date.now() function.

List of topics and their frequency:

• clock.minute.{YYYY].{MM}.{DD}.{HH}.{mm} every minute

• clock.hour.{YYYY].{MM}.{DD}.{HH}.{mm} every hour

• clock.day.{YYYY].{MM}.{DD}.{HH}.{mm} every day

• clock.dow.{day of week} every day, the third level of the topic is one in: "monday", "tuesday", "wednesday", "thursday", "friday", "saturday", "sunday", all lowercase

• clock.doy.{day of year} every day, the third level of the topid is the day of the year (0-365)

• clock.month.{month} every month, the third level of the topic is one in: "january", "february", "march", "april", "may", "june", "july", "august", "september", "october", "november", "december", all lowercase

• clock.year.{YYYY] every year

Installation

To run the service you can install with the -g flag and then run the glued-clock command:

$ npm install -g glued-clock
$ glued-clock

The clock will try and connect to the AMQP message bus using the default values, you can customise them by setting the GLUED_AMQP and GLUED_MESSAGE_BUS environment variables. You can find more information in the Glue Common Utilities documentation.
