Hi, Ioannis
Q ( Coulombs ) = I (A ) * t ( s )= C ( F ) * U ( V )
...
( 4.2 - 2.5 ) * 1 = 208 E-6 x t
>> t = 8173 s ...
That's all !
Nice general equation, indeed ... may I laugh a little ???
If your current draw was constant ... but just have a look to the curves at the end of the datasheet ...
You'll have some extra time !!!
BUT you must take into account the Supercap self discharge current ....
A look at the datasheet ... shows .... 315 µA ( Horror !!! )

So, You'll have some minus time ...
1.7 / ( 208 + 315 ) E-6 = 3250 Sec ...
Just hope an hour !!!

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
