2.25 inch LED display is easy to read and looks sharp in any Ham shack. Displays UTC Hours and 12 or 24 Hour Local Time. SetTimeout( updateClock. The CK-1000's unusually attractive and eye-catching LED display makes this a fine addition to any shack. Var result = days + ' ' + months + ' ' + dt.getUTCFullYear() + ' ' + h + ':' m + ':' + s ĭocument.getElementById( elementId ).textContent = result I actually recommend using a timeout of 16ms to keep lag to a minimum (so it's updated every frame on a 60Hz display and to mitigate clock jitter in the browser's JavaScript scheduler). Use a timeout of 500ms not 1000ms because it's the Nyquist-frequency of a clock at 1Hz and to reduce lag.As the month and day names are constant, they should be in a non-local (pseudo- static) variable.You don't need intermediate variables for all of the date components.Current Javascript programming conventions do not use snake_case for non-const identifiers, use PascalCase and camelCase instead. It is a web clock showing the official time of day from NIST, displayed as a 12 or 24-hour clock, in a user-selectable time zone.The timeout value should be a number literal, not a string.If you need to supply arguments then use to return a new Function object with presupplied arguments. You don't need to convert the function name to a string in setTimeout, just pass the function directly.innerHTML to set an element's text as this avoids an expensive reparse. getFullYear() should be getUTCFullYear().Use the UTC functions on the Date.prototype:.Use window.addEventListener('DOMContentLoaded', fn ) instead of blindly overwriting the onload property.Use var - otherwise you'll pollute the parent context with long-lived properties.The Local Time zone is shown as an offset from UTC, enabling you to ascertain when a particular activity occurred in either UTC or Local Time. The log file header indicates the Local Time zone that applied at the time that the log file was generated. With any feature or function that runs in Local Time and with which Geo SCADA Expert interacts, Geo SCADA Expert converts the time from UTC to Local Time as required ( see Time Zone Support in Geo SCADA Expert).Īny log files generated by Geo SCADA Expert show time values in UTC. BRG digital time zone clocks are capable of displaying all known world time zone rules, including rule based daylight saving time, 30 minute time zones, and more. Internally the Geo SCADA Expert server processes and stores time values in UTC. ![]() ![]() (With computers that are running Windows Server 2016 and newer operating system versions, high accuracy time can be achieved using W32Time, providing that certain criteria are satisfied. As such, high accuracy tolerances such as that mentioned above are outside of the design specification of the W32Time service. Windows Time uses the Simple Network Time Protocol (SNTP), which is a simplified version of Network Time Protocol (NTP). ![]() Therefore, for high accuracy environments (such as ones in which time needs synchronizing to within an accuracy of 1 to 2 seconds), use an NTP client to maintain accurate time, and disable Windows Time (W32Time). With such versions of Windows, the W32Time service is not a full-featured NTP solution. ATTENTION: This note only applies to machines that are running Windows Server 2012 R2 or earlier versions of Windows.
