Sunset times are off for Australia

[mhollanders]

Hi there,

The follow code gives me the wrong sunrise and sunset times for eastern Australia; Google tells me sunset is at 17:38 AEST (UTC+10).

getSunlightTimes(date = ymd("2023-09-15"),
                 lat = 28.865, lon = 153.565,
                 tz = "Etc/GMT+10",
                 keep = c("sunrise", "sunset"))

    date    lat     lon             sunrise              sunset

1 2023-09-15 28.865 153.565 2023-09-14 09:31:32 2023-09-14 21:53:54

Any idea what's going on?

Australia is in the Southern Hemisphere; latitude should be negative!

Hi, you're correct. -28.865, 153.565 still gives the wrong results.

    date     lat     lon             sunrise              sunset
