Clocks and watches are some of the most common time symbols. There are several clock and watch symbols available to copy paste including analog clocks, digital clocks, and stopwatch symbols. The analog clock symbols show the time in a traditional clock face format, with an hour hand, a minute hand, and sometimes a second hand. The digital clock symbols show the time in a digital format, typically with hours, minutes, and seconds separated by colons. Stopwatch symbols show a running timer, often used to time athletic events or races.
In addition to clocks and watches, we also have calendar symbols that represent days, weeks, months, and years.
Another time symbol in Unicode is the hourglass, which represents the passage of time.
