 ### {% linkable_title Time trigger %}
 
-Time can be triggered in many ways. The most common is to specify `at` and trigger at a specific point in time each day. Alternatively, you can also match if the hour, minute or second of the current time has a specific value. You can prefix the value with a `/` to match whenever the value is divisible by that number. You cannot use `at` together with hour, minute or second.
+The time trigger is configured to run once at a specific point in time each day.
 
 ```yaml
 automation:
   trigger:
     platform: time
+    # Military time format. This trigger will fire at 3:32 PM
+    at: '15:32:00'
+```
+
+### {% linkable_title Time pattern trigger %}
+
+With the time pattern trigger, you can match if the hour, minute or second of the current time matches a specific value. You can prefix the value with a `/` to match whenever the value is divisible by that number. You can specify `*` to match any value.
+
+```yaml
+automation:
+  trigger:
+    platform: time_pattern
     # Matches every hour at 5 minutes past whole
     minutes: 5
-    seconds: 00
 
 automation 2:
   trigger:
-    platform: time
+    platform: time_pattern
-    # When 'at' is used, you cannot also match on hour, minute, seconds.
+    # Trigger once per minute during the hour of 3
-    # Military time format.
+    hours: '3'
-    at: '15:32:00'
+    minutes: '*'
 
 automation 3:
   trigger:
-    platform: time
+    platform: time_pattern
     # You can also match on interval. This will match every 5 minutes
     minutes: '/5'
-    seconds: 00
 ```
-<p class='note warning'>
-  Remember that if you are using matching to include both `minutes` and `seconds`.  Without `seconds`, your automation will trigger 60 times during the matching minute.
