Shadergraph Day-night cycle

I have a lighting manager script that handles increasing the time of day (a float between 0-24) and makes adjustments to my skybox shader (custom through shadergraph) and for the most part the script and shader work perfectly unless the time of day is less than ~0.001 (00:00:03.6 for the in-game clock) or greater than ~23.994 (23:59:38.4 for the in-game clock) where the lighting goes wonky, I have no idea what is causing this problem so I'll attach all the assets included as opposed attempting to post screenshots and code of almost everything.
