XF 2.3 Is the 'System' variation of dark/light theme reversed?

[CZ Eddie]

Here on Xenforo you can select light, dark or "system". With system following your computer/phone's default.
Where during the day you should see a light theme and at night a dark theme.
But the XF2.3 system seems to be reversed.
I'm getting dark theme during the day and light theme at night.
