Name: World Clock
Mac Platform: Intel
OS version: 10.9 or higher
1.2.1 Added drag & drop for clock faces, sorry for the temporary inconvenience, you can now re-arrange clocks in any order you want.
Simple and powerful world clock:
• Add cities and timezones like GMT and UTC with a few key strokes.
• Convert international time with a drag of a cursor.
• Schedule international calls and meetings and add them to your calendar.
• Add Interactive Widget to your Today's View (OSX Yosemite only): quickly peek and see what time it is in the other location, drag the line to convert time, so you can find a time that suits quick, without getting distracted from whatever you were doing.
Easily tell what time it is with clocks that change color with time of day:
— black for evening and night,
— white for morning, and
— green for working hours.
