Environments Time Of Day has a bug

Time of Day has Bug!

For example the time is 2:37PM

I didn’t edit anything of it,
just change the time!

even 12:00 afternoon, the shadow is WRONG!

Please check my record video:

Hello @sinsin55duck! From you video, it looks like you are using the Hong Kong preset for the latitude and longitude. Could you let me know the latitude and longitude coordinates of your model placements? Also, it would help if we could take a look at your source file. You can email it to me here: omniversecommunity@nvidia-omniverse.atlassian.net
