 Beginning and ending dates are roughly the reverse in the southern hemisphere . For example , mainland Chile observed DST from the second Saturday in October to the second Saturday in March , with transitions at 24 : 00 local time . The time difference between the United Kingdom and mainland Chile could therefore be five hours during the Northern summer , three hours during the Southern summer and four hours a few weeks per year because of mismatch of changing dates . 

entailment
 The name of local time typically changes when DST is observed . American English replaces standard with daylight : for example , Pacific Standard Time ( PST ) becomes Pacific Daylight Time ( PDT ) . In the United Kingdom , the standard term for UK time when advanced by one hour is British Summer Time ( BST ) , and British English typically inserts summer into other time zone names , e.g. Central European Time ( CET ) becomes Central European Summer Time ( CEST ) .
