Hi ScraPerfect,
Thanks for your question. So, we need to determine why your MacBook Pro is not resetting the time in the area you are travelling, is that right?
Are you still running OS X Mavericks on your computer? Have you updated to the latest version of OS X Mavericks?
The first thing I would suggest is to reset your Date/Time settings in System Preferences. Click the link below for complete details:
If the wrong date or time is displayed in some apps on your Mac
Remove the checkmark in front of "Set time zone automatically using current location"
Next, try turning off Location Services.
About Location Services in OS X and Safari
Finally, restart your computer and enable "Set time zone automatically using current location" and enable Location Services again in System Preferences.
ScraPerfect, if these two troubleshooting steps do not resolve your issue, please reply with any additional information you can about your situation, and we'll continue to investigate.
Take care.
