On the continental US there's 4 time zones, Pacific, Mountain, Central, and Eastern.
Right now in Seattle (PDT) it's 3:10pm, and as you move eastward each time zone it goes up one hour (Mountain is 4:10, Central is 6:10, Eastern is 7:10).
Of course pretty sure Alaska (UTC-9) and Hawaii (UTC-10) have their own time zones as well so really the US has 6 time zones.
