For example, the gap of Feb 1 and Mar 1 is 1 month. But output was "0 month 28 days" in timezone Asia/Tokyo. ("1 month 0 days" in timezone UTC) Test script: --------------- https://wandbox.fetus.jp/permlink/zgdq2iE1VuL9zM50 Expected result: ---------------- a: 2015-2-1 <--> 2015-3-1 DateInterval Object ( [y] => 0 [m] => 1 [d] => 0 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) b: 2015-3-1 <--> 2015-3-29 DateInterval Object ( [y] => 0 [m] => 0 [d] => 28 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) c: 2015-4-1 <--> 2015-4-29 DateInterval Object ( [y] => 0 [m] => 0 [d] => 28 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) Actual result: -------------- a(Asia/Tokyo): 2015-2-1 <--> 2015-3-1 DateInterval Object ( [y] => 0 [m] => 0 [d] => 28 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) b(Asia/Tokyo): 2015-3-1 <--> 2015-3-29 DateInterval Object ( [y] => 0 [m] => 1 [d] => 0 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) c(Asia/Tokyo): 2015-4-1 <--> 2015-4-29 DateInterval Object ( [y] => 0 [m] => 0 [d] => 28 [h] => 0 [i] => 0 [s] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => 28 [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71826&edit=1
