In creating a custom filter in request view, I try to create a filter that says "Technician is me" and "Last Update Time is <some date>".  It would look something like this:

However, after hitting Save, then going back in to edit the filter, it has changed the date by one day:

It also happens when using "Created Time" . . . it happens when using "Greater or Equal" . . . it does NOT happen when I use "Greater".

It just seems that there is something super odd going on here.  I can't think of any reason it should change the date I enter.  We're on build 9311.
