If you consider this as an option, you should add the seconds offset!
Until 1978 (?) for some applications, Paris time was in official use;
and it's defined as GMT+00:09:21 (I don't know what happen with the 10
leap seconds on 1972-01-01 ;-).
On the other side, I don't consider it's worth the value, if you want MHO.

I won't count India as a small country :-), but I understand this is the
very reason for this country to be in a half-hour offset (I think the
other options is to have two time zones, clearly a bad thing, or
advantaging a side of the country instead of the other...)
