Otherwise known as a clock, a Timepiece "is an instrument used for indicating and maintaining the time and passage thereof." Large or small, digital or analog, ancient or modern, humble or ornate, they are everywhere. So, there should be no shortage of subject matter for this project!
Participating in this Utata project is simple! You need to do/have the following three things and then all you have to do is tag your photos utata:project=timepiece (read about other tagging options) and you're all set! Have fun!
