*
* FUNCTION: SelectTimeZone
*
* DESCRIPTION: Display a form showing a time zone and allow the user
* to select a different time zone. This is the time zone
* dialog as seen in Date & Dime panel
*
* PARAMETERS:
* ioTimeZoneP <-> pointer to time zone to change
* ioLocaleInTimeZoneP <-> Ptr to locale found in time zone.
* titleP -> String title for the dialog.
* showTimes -> True => show current and new times
* anyLocale -> True => ignore ioLocaleInTimeZoneP on entry.
*
* RETURNED:
* true if the OK button was pressed (in which case *ioTimeZoneP and
* *ioCountryInTimeZoneP might be changed).
*
* HISTORY:
* 03/02/00 peter Created by Peter Epstein.
* 04/03/00 peter Allow NULL currentTimeP.
* 04/12/00 peter API changed to get rid of trigger text
* 04/14/00 peter Update current & new time as time passes
* 07/31/00 kwk Use SysTicksPerSecond() routine vs. sysTicksPerSecond macro.
* kwk Re-wrote to use set of resources (name, offset, country),
* scrollbar vs. arrows, etc.
* 08/01/00 kwk Support scroll-to-key. Fixed scrollbar/list sync bugs.
* 08/02/00 kwk New API w/ioCountryInTimeZoneP and anyCountry parameters.
* kwk Call FrmHandleEvent _after_ our event handling code has
* decided that it doesn't want to handle the event, not before.
* 08/03/00 kwk Call LstSetListChoices before calling LstGetVisibleItems,
* as otherwise accessing the time zone picker from the
* Setup app (when <showTimes> is false) gives you a two-
* line high display because LstGetVisibleItems returns 0.
* 08/18/00 kwk Play error sound if user writes letter that doesn't
* match any entries.
* kwk Don't select item if doing scroll-to-view for entry
* that matches the letter the user wrote.
* 08/21/00 kwk Scroll-to-view with text entry now scrolls to the top
* of the list, versus the middle.
* 10/09/00 peter Get rid of scroll bar and let list do the scrolling.
* 11/17/00 CS Change ioCountryInTimeZoneP to ioLocaleInTimeZoneP,
* (and anyCountry to anyLocale, but that doesn't matter),
* since CountryType is only a UInt8, and this may
* change someday.
