Linux – Configure time zone and daylight savings
So, you setup your new Linux distribution and used all the default setting during the install.
but now, you realized that you are on different time zone or you want to check if the DST change will occur on the right dates.
here is a simple and solid solution that set your system time zone.
Check system DST Database
shows when the system is configured to change the next DST: on the time zone “US/Eastern”
/usr/sbin/zdump -v US/Eastern | grep 2015
Not sure how to type your specific time zone? (Folder/file)
find your Time zone location
ls /usr/share/zoneinfo/ cd yourDesiredTimeZone
Configure time zone to Eastern time and allow time zone change automatically.
this removes the current localtime file
creates a link to the correct time zone file
ln -s /usr/share/zoneinfo/US/Eastern localtime
with this approach when the DST tables are updated (there are some countries where it changes frequently) your system will be updated too.
