Does Daylight Saving Time change the name of standard time zones?

Answer 1

DST and Time ZonesYes, time zone names typically change when DST is observed.

American English replaces "standard time" with "daylight time": for example, Pacific Standard Time (PST) becomes Pacific Daylight Time (PDT).

The timezones themselves don't change ... The Pacific Timezone, for example, remains even when the clocks there are at PST+1.

The name "Summer Time" is far more popular around the world than the name "Daylight Saving Time" for the semiannual clock adjustments. Countries that use that name add the word "Summer" before the word "Time" to differentiate between their two time offsets. For example, Central European Time (UTC+1) becomes Central European Summer Time (UTC+2), and Brasilia Time (UTC-3) becomes Brasilia Summer Time (UTC-2).

Answer 2

No, Daylight Saving Time does not change the names of standard time zones. Standard time zones remain consistent throughout the year, while Daylight Saving Time affects when we adjust our clocks to make better use of daylight hours during certain periods.
