We need to automatically  add  sunset time to our surveys. One way is using pulldata with preloaded list of sunset time by date.  Or is there some other way?  We are using disconnected Survey 123.  Getting a consistent sunset time across all Survey users has been a long term problem that the user would put in a sunset time.  Lots of user induced #SUNSET

Hi Peter, 

Based on Sunrise equation - Wikipedia , it appears possible to implement using a series of calculations in an XLSForm.
