World Time lets you display the current time in any one of 30 cities
(29 time zones) around the world.

When you enter the World Time Mode, the screen for the city that
was displayed when you last exited the mode appears first.

The seconds count in the World Time Mode is linked with the
Timekeeping Mode seconds count.

The same 12-hour/24-hour format you select for the Timekeeping
Mode time is also applied in the World Time Mode.

Important!

If the World Time Mode time is incorrect, ajust the setting of the
current time in the Timekeeping Mode. See “Setting the Time and
Date Manually” for more information.

Using Summer Time (DST)

Summer time, or Daylight Saving Time (DST) as it is called in
some countries, calls for setting clocks ahead one hour during the
summer season. Note that the use of summer time depends on
the country and even the local area.

summer time is turned on.

You can turn summer time on or off
independently for each World Time
Mode city. Note, however, that you
cannot turn on summer time for the
“GMT” city code or the city code
selected as your Home City.

Time Stamp Mode

DST Indicator

The Time Stamp Mode lets you create and store up to 10 records, each of which contains the date (month and day) and time (hour,
minute, second) that the data was stored.  Time Stamp records serve as helpful memos when you need to remember the current date and
time for some reason.

Entering the Time Stamp Mode causes a standby screen to appear.

The same 12-hour/24-hour format you select for the Timekeeping Mode time is also applied in the Time Stamp Mode.

standby screen reappears.

You can have up to 10 Time
Stamp records in memory at one
time.

Creating a Time Stamp record
