  4. Date of the city.

Time Bar

By scrolling of Time Bar, the time of all cities changes automatically.
  -Upper direction : future
  -Lower direction : past

Come back to current time with Current Time Button.

When you double-tap Time Bar, you can change the time by a unit for one hour.
The color of icons on Time Bar is clear when a unit of time is one hour.
If you double-tap a Time Bar once again, you return to a unit for one minute.

Date and time designation

You can designate the date and time directly when you tap the area of each city.

Delete and reorder cities

Cities can be deleted or rearranged by tapping the “Edit” button in the upper left corner of the screen.

Addition of the city

A city list is displayed when you tap “+(plus)” button of the screen top right corner.

Editing a city

Press and hold on a city to open the menu.
Select “Edit City” from the menu to edit the city.

Press “Change city” to display the city selection screen, and select the city you want to change.

You can change the name of the city or country to any name you like by entering a string in the “Custom Names” section.

An indicator appears before the name of the city for which the custom name is set.

Show Fixed City

If you turn on the “Enable Fixed City” option in the settings, only one fixed city will be displayed at the top of the screen.
Like other cities, you can directly specify the date and time, change the city, and set a custom name for the fixed city.

About Time Difference Data in “World Clock”

Basically, “World Clock” does not store time difference data within the application.
The time difference data for each city is obtained by contacting the Android OS side, and the time difference data on the Android OS side is directly reflected in the time displayed on the “World Clock”.
Please refer to this page for details.


Q : Is it reflected automatically in daylight saving time?
A : Yes.
So, you don’t need to do some special operations when the beginning or ending of daylight saving time.

Q : I found the wrong time. What should I do?
A : I’m sorry to trouble you, but please contact RandyApps.
Fundamentally, our “World Clock” app doesn’t have any time difference data in it. “World Clock” inquires time difference to Android OS, so our app shows you the time which is based on the data of Android OS.
Therefore, if there are some wrong time, we need to find out if the cause is due to our bug or the data of Android OS.
Thank you for your kind cooperation.
