Why does my Astrobinding not follow the offset declared in Paper UI

I am sorry but it cant put in a time in the range event at earliest or latest, when i put a time at earliest say 18:00 and 18:30 at latest i get warnings in the log like below


2020-11-19 15:43:42.882 [WARN ] [ng.astro.internal.util.DateTimeUtils] - Can not parse astro channel configuration '1970-01-01T17:30:00.000Z' to hour and minutes, use pattern hh:mm, ignoring!
2020-11-19 15:43:42.887 [WARN ] [ng.astro.internal.util.DateTimeUtils] - Can not parse astro channel configuration '1970-01-01T17:30:00.000Z' to hour and minutes, use pattern hh:mm, ignoring!

It is referring to the first of januari in the year 1970 ???

But i dont know why, from where is this coming ?

Btw, i am doing this in paper ui, i am not using text files.
