There is no subsecx being modified in the utc_to_local call below this, and I'm not sure why you would want to add in the fractional seconds unless you assumed the timezone conversion would drop the existing fractional seconds (TZInfo doesn't drop fractional seconds). Subsecond of Time::tm should be 0 git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_6@67934 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

For example, `TIme.new(1933)` returned a wrong time whose year is 1922 in Asia/Kuala_Lumpur because there is no 00:00:00 1st Jan. 1933 in the time zone. ``` $ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)' 1932-12-31 00:00:00 +0700 ``` This change fixes the issue by using `DIV` macro instead of `/`. Now `Time.new(1933)` returns a time in 1933. ``` $ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)' 1933-01-01 00:20:00 +0720 ``` [Bug #16159] Added a test for [Bug #16159] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_6@67836 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* time.c (time_localtime): check if `vtm.zone` is a simple zone name string before trying to call the conversion method. since r64952, `Time.getlocal` on UTC time has lost the performance about 45%, due to this call. the performance is about 90% of r64951 by avoiding it. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65360 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* time.c (zone_str): while rb_fstring_usascii and the family require that the argument string is never modified, tzname may point areas which will be discarded by calling tzset(). make a String then call rb_fstring to copy the zone name. when an ID equals TZ environment variable, its name string also has modified by changing tzname. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65035 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
