What is the difference between Dialogflow ES and Dialogflow CX pre-built nodes?

Dialogflow CX represents an advanced iteration of ES. Dialogflow ES is best suited for simpler chatbot applications, whereas Dialogflow CX is tailored for intricate, multi-turn conversational experiences, particularly in enterprise-level settings. The choice between the two depends on the specific requirements and complexity of the project at hand.

See here for more information about migrating from Dialogflow ES to Dialogflow CX.

How is my File Rotation affected by DST (Daylight Savings Time) in Logbooks?

Let's try to understand the behaviour with the help of an example.

Assume that you have configured a schedule in the logbooks and the time zone selected in Rotation Policy is included under DST (Day light saving time zone). In this case, there is a possibility that the scheduled file delivery can be skipped because of DST adjustment in the time zone.

For instance, say you are in Ireland, where daylight savings events occur at 3:00 AM, GMT. If you have a logbook schedule that initiates everyday at 3:15 AM, then on the day of the beginning of daylight savings time, the schedule will be skipped, since, 3:15 AM never occurs that day. If you have a schedule that triggers every 15 minutes of every hour of each day, then on the day and time that daylight savings ends, there will be an hour of time for which no schedule executes. This is because, when 3:00 AM arrives, it will become 1:00 AM again, however all of the scheduling during the 1:00 AM hour has already occurred, and the trigger’s next initiation time was set to 3:00 AM. This is why, for the next hour, no schedule execution will occur.
