FAQ
What is true solar time used for here?
LifeSense uses true solar time as a calculation basis when exact local time and location are available and the supported engine needs that basis.
Can true solar time estimate my missing birth time?
No. It adjusts a known time by location-based basis. It cannot recover an unknown hour.
Will the export show the time basis?
Yes. When available, the export can include timezone, location, true solar time basis, and time-confidence labels as chart facts.
