@sk25 You need to have Location Services and automatically set time zone enabled on a Mac for it to automatically adjust time. The following script will set that up (you'll want to restart the Mac to ensure the changes take effect):

#!/bin/sh

uuid=$(/usr/sbin/system_profiler SPHardwareDataType | grep "Hardware UUID" | cut -c22-57)
/usr/bin/defaults write /var/db/locationd/Library/Preferences/ByHost/com.apple.locationd.$uuid LocationServicesEnabled -int 1

/usr/bin/defaults write /Library/Preferences/com.apple.timezone.auto Active -bool YES
/usr/bin/defaults write /private/var/db/timed/Library/Preferences/com.apple.timed.plist TMAutomaticTimeOnlyEnabled -bool YES
/usr/bin/defaults write /private/var/db/timed/Library/Preferences/com.apple.timed.plist TMAutomaticTimeZoneEnabled -bool YES
/usr/sbin/systemsetup -setusingnetworktime on

exit 0

@sdagley for information, you can use the following commands to take changes into account immediately

/bin/launchctl kickstart -k system/com.apple.locationd
/bin/launchctl kickstart -k system/com.apple.timed
