Are there any countries whose law still prescribes the time zone as a meridian (that may be a multiple of 15, but arguably still can't be "legally correctly" described as GMT±N since it gives the difference in degrees rather than hours), e.g. "the mean solar time of the sixtieth degree of longitude west from Greenwich"?
Argentina, for one http://servicios.infoleg.gob.ar/infolegInternet/anexos/135000-139999/136191/... but as with many other places, the observatory tasked with providing Argentine legal time has the leeway to interpret that as offset in SI seconds from UTC rather than fractions of one earth rotation from GMT.
The US law doesn't currently, but I can't find when it changed.
