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.
