Locales that observe Daylight Saving Time (DST) set their clocks ahead one hour for a portion of the year for DST, then return their clocks to standard time by setting the clocks back.

Teradata Database can automatically account for DST time switching through the use of time zone strings. Time zone strings allow the definition of named time zones for locales based on their time offset from UTC. For locales that observe DST, time zone strings can include rules that define when DST starts and ends. Teradata Database uses this information to determine appropriate handling of time and date information, and to automatically adjust time zone offsets as appropriate for locales that observe DST.
