Why was the default time for Date questions changed from 12AM to 12PM? We have a date question with a constraint .< now() that started failing for any surveys created before noon. This issue started since last weeks update of Survey123 for iOS. I checked my geodatabase and noticed the change in default time from midnight to noon.
As Doug mentioned, the change to 12 noon local time for the 'today' mark was made to accommodate time zone issues, particularly:
- Consistency of day across a daylight savings switch (when the time 'falls back', previous results will be seen as the previous day)
- Consistency of day when viewing results that were collected across time zones (the 12 noon solution works well continental-level collections, which can span up to 7 time zones)
