# Time and Date

## Overview
- The "Time and Date" module in your KNX device, equipped with a real-time clock backed by a supercapacitor, ensures accurate timekeeping even during power outages.
- This module allows for precise configuration of the device's location settings, daylight saving adjustments, and other time-related functions.

## Key Parameters

### General Settings
- ***Battery Status Indication***: Activates an object that displays the battery status as a percentage.

### Location and Time Settings
- ***Select Continent***: Choose the continent. If set to "not selected," manual input for "time zone," "latitude," "longitude," and daylight saving settings is required.
- ***Select City***: City selection can be set to "custom." In this case, "time zone," "latitude," "longitude," and daylight saving settings must be manually entered.
- ***Time Zone***: Select the time zone based on the device's geographical location.
- ***Latitude***: Input for the device's latitude coordinate.
- ***Longitude***: Input for the device's longitude coordinate.

### Daylight Saving Settings
- ***Automatic Transition to Daylight Saving***: Choose whether the device should automatically adjust for daylight saving based on its location.
- ***Date of Transition to Daylight Saving Time***: Set the date when daylight saving time starts.
- ***Transition to Daylight Saving Time***: Set the hour when daylight saving time starts.
- ***Date of Transition to Standard Time***: Set the date when standard time resumes.
- ***Transition to Standard Time***: Set the hour when standard time resumes.

### Time and Date Transmission Settings
- ***Send Time to KNX Cyclically***: Configure how often the time (in hh:mm:ss format) is sent to the KNX bus. Setting it to '0' stops the transmission.
- ***Send Date to KNX Cyclically***: Set the frequency of sending the date (in hh:mm:ss format) to the KNX bus. '0' disables this feature.

### Astronomical Time Settings
- ***Sunrise Time Object State***: Activates an object to send sunrise time calculated based on the device's coordinates to the KNX bus.
- ***Sunset Time Object State***: Enables sending of sunset time to the KNX bus.
- ***Moonrise Time Object State***: Activates sending of moonrise time to the KNX bus.
- ***Moonset Time Object State***: Enables sending of moonset time to the KNX bus.
- ***Culmination Hour of Sun Object State***: Sends the time of solar noon based on the device's location to the KNX bus.
- ***Twilight Hour Object State***: Activates an object to send twilight hour information to the KNX bus.
- ***Dawn Hour Object State***: Enables sending of dawn time to the KNX bus.

### Advanced Time Settings
- ***Time Zone Object State***: Makes the device's time zone information readable and adjustable via an object. The write flag must be active for modifications.

## Purpose
- To ensure accurate and location-specific timekeeping in your KNX system.
- To provide flexibility in managing time-related functions, including daylight saving adjustments and astronomical event timings.

## Usage
- Set up the "Time and Date" module during the initial configuration of your KNX device using ETS software.
- Ideal for automating actions based on precise time and date information, enhancing the efficiency and functionality of your smart home or building systems.
