Under the hood, if I’ve understood things correctly, there is no such thing as only a date or only time. There are timestamps and a timestamp is a date and time in one object.
And there are tons of difficulties related to timestamps (a date-time) because first these are displayed differently depending on region, device, etc. and second at a given timestamp (like “now”) the timestamp is are actually different based on where you are on the planet (time zones).
I think that sums up the difficulty and might help your understanding, though it might not help solve your issue.
Do you happen to be 2 hours off GMT?
If so, perhaps you could adjust for this 2-hour time difference by using a math column.
