This program is for travelers and all the other persons who need to co-ordinate their time in the current location city and the other target city.

Being a plug-in to Calendar program, Time Zone changes appointment start time so that in current city it corresponds to the time of appointment in its "native" city, which will be selected by user.

This correction provides correct displaying of appointment start time after setting of "native" city as current one in Clock program ("Start/Settings/System/Clock/Time").

Time Zone adds also supplementary text to Location property of the appointment.
This gives a user possibility to see "native" city for the appointment and it's time in this city.

Update Description:
v1.1:

• The problem of daylight saving time (DST) is solved in the program - but in part only. It changes start time of the appointment using shift between time zones (e.g., we have 6 hours shift between GMT-05.00 and GMT+01.00 time zones) and information from new check boxes. Previously program considered that current and target cities had the same DST status. Main dialog window of the program has check boxes that allow user to show separately if DST is used in the city of current location and in target city. So, responsibility for DST correction falls on user.
  When setting DLT for current and target cities user should take into account that difference between DLT for source city (1 if set) and DLT for target city (1 if set) is used in correction of start time of the appointment. So, if both source and target cities have the same DLT user could leave both check boxes unchecked (or checked).
• DST settings selected by user for the check boxes are stored in the registry.
  
• Clarified the program behaviour for time change of previously processed appointment.
  
  • Let the program is used for the same target city that is already mentioned in TimeZone notes for Location property of appointment. Then the program consider that user have selected new time for the same target city and modifies the time in Calendar for current city accordingly.
  • Let user executes the program for the other target city than the one mentioned in notes for Location. Then program will use the time mentioned in TimeZone notes as the base.
  • If you would like to set new appointment time for new target city then when editing the appointment time you should delete TimeZone note from Location property of the appointment. TimeZone will create new note for your new target city.
• Bug fixed: when DST is used, time correction for all-day events was made as for standard time, i.e. by 1 hour less than it should be.
• Bug fixed: despite the message "Invalid timezone information for current city. Correction will be cancelled." invalid appointment time correction was made.
