==== Hourly Schedule

A <<trigger-schedule, `schedule`>> that triggers at a particular minute 
every hour of the day. To use the `hourly` schedule, you specify the minute (or minutes)
when you want the scheduler to start the watch execution with the `minute` attribute. 

NOTE: If you don't specify the `minute` attribute for an `hourly` schedule, it defaults to `0` and the 
schedule triggers on the hour every hour--`12:00`, `13:00`, `14:00`, and so on.

===== Configuring a Once an Hour Schedule
To configure a once an hour schedule, you specify a single time with the `minute` 
attribute. 

For example, the following `hourly` schedule triggers at minute 30 every hour--
`12:30`, `13:30`, `14:30`, and so on. 

[source,json]
--------------------------------------------------
{
  ...

  "trigger" : {
    "schedule" : {
      "hourly" : { "minute" : 30 }
    }
  }
  ...
}
--------------------------------------------------

===== Configuring a Multiple Times Hourly Schedule

To configure an `hourly` schedule that triggers at multiple times during the hour, you specify
an array of minutes.  For example, the following schedule triggers every 15 
minutes every hour--`12:00`, `12:15`, `12:30`, `12:45`, `1:00`, `1:15`, and so on.

[source,json]
--------------------------------------------------
{
  ...
  "trigger" : {
    "schedule" : {
      "hourly" : { "minute" : [ 0, 15, 30, 45 ] }
    }
  }
  ...
}
