Assuming you are in EST you can do it using the following
The code I provided will convert from UTC (which is what Now() will give you) to the user's current time zone. There is no easy way to convert to a specific time zone using Power Apps alone. There is a function in Power Automate that can be used to convert to a time zone by name, but that function doesn't exist in Power Apps. So you could call a flow to do the conversion and give you back the value.
