Theoretically 15 degrees wide. I think you will be able to find some times
zones that are over 20 degrees at their widest points. The Eastern time
zone in the US is a good example. It runs from *about* 66 degrees in Main
to over 86 in western lower Michigan. "I think" the upper Peninsula is also
eastern all the way to the West end. If it is all the way to the west end
then it's 90W for a width of 24 degrees. OTOH the boundaries are not any
where near straight.
At any rate whether the figures are correct or not time zone widths do vary
considerably.

As you emphasized the [or more] the meridian may not be centered.
For instance the meridian for Eastern Time *should* be 75 degrees (a
multiple of 15 degrees or one hour), but 75 degrees is very close to
philadelphia with the western edge of lower Michigan being 86 degrees or 21
degrees west of the meridian. It'd be over an hour off for the sun being
due south at noon. OTOH any one know what time zone Tennessee is in?
