![]() ![]() This makes it easy, for example, to eliminate the hours component from the output just by removing it from the line. We'll handle milliseconds a little differently, taking advantage of the built-in JavaScript function toFixed(), which is used to convert a number to a string with a fixed number of decimal places.įinally, we'll set up the expression so that the last line is where all the parts get assembled into the final output string. Twenty four hour time does not use 'am' or 'pm', but courts hours from midnight (0 hours) to 11 pm (23 hours). Daylight savings time adds 1 hour to the local standard (real) time. Time in other locations will be the UTC time hour plus or minus the local Time Zone. ![]() That way we'll end up with a two digit string for each component. UTC time is the local time at Greenwich England. It is within about 1 second of mean solar time at 0° longitude 1 it does not observe daylight saving time. Otherwise, if we defined clockStart as a string like "00:00:00.000", we'd just have to write code to convert it to seconds anyway.įor each of the hours, minutes, and seconds components, we'll run them through a function (we'll call it padZero()) which will convert the value to a string and add a leading zero if necessary. Coordinated Universal Time (French: Temps universel coordonné), abbreviated to UTC or CUT, is the primary time standard by which the world regulates clocks and time. Since time values in After Effects are always represented as seconds, that's what we'll use here. The variable clockStart will represent the starting time of our clock. Loran time was zero at 0h and since it is not perturbed by leap seconds it is now ahead of UTC by. Since rate is a multiplier, if we set its value negative, the clock will count down. GPS time was zero at 0h and since it is not perturbed by leap seconds GPS is now ahead of UTC by Loran-C, Long Range Navigation time, is an atomic time scale implemented by the atomic clocks in Loran-C chain transmitter sites.

An electronic component called a quartz crystal sets the frequency of the oscillator to about 32768 Hz with a high degree of accuracy. In the case of the oscillator in a clock, this runs at several thousand hertz or cycles per second. So if we want it to count at the same rate as a wall clock, we'd just set it to one. Desktop Clock is a simple, resizable, customizable, clock app. An electronic oscillator generates a voltage signal that repeats itself at a set frequency. The variable rate will be a multiplier for how fast our clock counts compared to real, or comp, time. At the beginning of the expression we'll define two variables, rate and clockStart. In that expression we'll calculate the different components (hours, minutes, seconds, and milliseconds) that represent the current time of our clock. The most reasonable approach will be to develop an expression for the source text property of a text layer. ![]()
