Determining Aircraft arrival times

Hello:
I've spent a good while searching thru forums and websites trying to
figure this one out, so I'm hoping that someone who knows how to make
this work will chip in.
I work with aircraft arrivals to worldwide destinations, so lots of
time zones can be factored in to the answer. My tracking system gives
me the time in minutes that the aircraft will take to reach it's final
destination, for example 408 minutes. I've converted that to hours, no
problem. I would like to use the =now() function to get the current
local time, but it displays the date as well in the particular cell. I
can then add those two times and get a reasonably good answer. However,
when I try to convert the times from local time to GMT (or Zulu/UTC), I
keep getting errors. I'm in Washington, DC which is 4 hours behind GMT.
I'm thinking that its reading the cell as a formula and not a value, so
I have to go manually from there to convert to different time zones. Am
I missing some easy but elusive step?

Thanks in advance......

You don't provide enough information to know what the problem is. So you
probably missing something simple.

What kind of error? What are the formulas you are using.

To convert EDT to UTC:

=NOW() + TIME(4,,)

or

=NOW() + 4/24
