Standard Time in Chile

Wouldn't it make more sense to include Chile within the UTC-3 zone, since that is their standard time zone?
Chile does use UTC-4, but only for three month in the winter. Marxolang (talk) 07:03, 3 November 2016 (UTC)

Note that some zones (e.g. Eire) do "negative daylight-saving time" – i.e. their standard time is what they use in summer, but their winter time is still offset an hour before summer time (i.e. clocks skip an hour in spring and repeat one in autumn); they just chose to describe the winter time as the DST (with a negative offset). If the map purports to display countries by their standard zone offset, such zones should show their summer time, as that's standard time, not their winter time (even though most zone's standard time is winter time). The duration of either is, however, beside the point: the fact that Chile only uses its winter time for a quarter of the year has no bearing on which is its standard time. As it happens, Chile's standard time is indeed its winter time; and this year (in Santiago) it's in use Apr-Sep (five months) rather than the May-Aug (three months) it has indeed used in some recent years. The situation is further confused by 2015, when Chile stuck to summer time all year; and by Punta Arenas doing the same also since 2017 (even though it's further from the equator, making the alleged benefits of messing with clocks more pronounced there). None the less, CLT = UTC-4 is Chile Standard Time, so is properly what to display on the map (even in a year when none of the country is using it). It might indeed make more sense for Chile to redefine its time-zone to use its current summer time as standard time and have a separate CLWT for winter time (in so far as any part of the country opts into it), but that is for Chile to decide, not the maintainers of this map. 84.212.163.209 (talk) 14:50, 7 April 2019 (UTC) Eddy.
