next_setting Sun always shows today - 1

[dmoore19]

Maybe I'm missing something here, but when I try to get sunrise and sunset for a particular date, sunset always gives a datestamp of the prior day's sunset.

location = ephem.Observer() 
location.lat = '28.03' 
location.long = '-97.07' 
location.date = '2023/03/01' 

sun = ephem.Sun() 
sun.compute(location) 
sunrise = location.next_rising(sun)
sunset = location.next_setting(sun)

print ("Sunrise ", ephem.localtime(sunrise) )
print ("Sunset ", ephem.localtime(sunset))

Output:
Sunrise 2023-03-01 06:52:46.682412
Sunset 2023-02-28 18:28:08.477292

I've tried with many dates, sunset always showing the prior day. What am I doing wrong?

You are setting the date to UTC midnight, which appears to be before your local sunset. Try midnight in your own timezone.
