Comfigurator 2.2.3 has Sunrise and Sunset times. Go to Schedule > Sunrise/sunset,  see screenshot below.  Note that firmware 5.121 is  needed for this feature
 
Select the City from the drop-down list. If the city is not listed, enter the lattitude and longitude/ Click  the "SET TIMES" button on the bottom of the screen

The table on the left shows the sunrise and sunset times for each week of the year
Weeks are calculated from 1st January as Day 1, hence weeks can start on any day of week not just Monday

The sunrise and sunset times shown are NOT adjusted for daylight saving. That means that when daylight saving is on, the sunrise and sunset times are 1 hour later than the times shown.

These sunrise and sunset times are obtained from freely available sources. This may not agree with other sources on the Internet. Please check the times for the City selected. The times can be changed for each week.

The purpose of the sunrise and sunset times is to
1 - Activate Sunrise and Sunset times at the correct times in the sunrise/sunset table. Go to Misc Events to see the sunrise and sunset responses.

2 - Set the Night time flag after sunset and before sunrise. This can be used in the Action If Night Time.. to allow things to be done at night.

Comfort automatically changes the time forward or backwards at the dates given in the Daylight saving section (Start Date and End Date). This takes place at 3 AM on the day of week, normally Sunday shown on the tables. Sunrise and sunset times are changed accordingly so that sunrise and sunset occurs at the correct times regardless of what date it is

You can test the sunrise and sunset times by setting the time to 1 minute before sunrise or sunset and waiting for the next minute.

When you save the file and open it again later, the City is not shown, but the  sunrise and sunset times are maintained. You can also upload (Comfort to PC) the sunrise/sunset times in Comfort
