![]() ![]() If the local clock drifts, the displayed server time will also drift over time until it syncs to the server once again. After getting an initial reading of the time from the server, the “server time” is actually derived from the local time and an offset.While such processing doesn’t take much time, it may add several milliseconds depending on workload. There is also processing delay on both the server and client.UTC is used to ensure that all time is the same, regardless of where in the world it is being measured. UTC is based on the time of the prime meridian (0° longitude) and is adjusted to account for leap seconds. It is a 24-hour clock that is used for international timekeeping. This is largely corrected by timestamps sent between the client and server, but these timestamps in themselves can be inaccurate. UTC (Coordinated Universal Time) is the international standard for time. First, there is varying path delay, or network latency, between the server and your browser.The live clocks on this site are meant to represent the time on a time server, and their accuracy is dependent on a variety of factors. We tried this by publishing a new test service, but it made no difference.In layman’s terms, accuracy is how closely a clock matches an accepted reference clock. The answer according to several blogs and Geonet posts appeared to be to set a timezone when publishing the feature service. Meaning the stored date, when compared to the other UTC times, is 13 hours ahead of what it should be. However, if the same datetime is entered via Pro, this is stored directly as-is into the database. When we update a date using the standard ArcGIS Online map viewer or Collector, the datetime picked will be in our local timezone (happens to be Auckland, NZ) and the date is converted and stored in UTC time (currently 13 hours behind) which, to us, is correct and is what we expect. We have noticed that, when updating date fields, the raw date that ends up stored in the feature service is different depending on whether the method used to enter the date was Pro vs other applications. Using ArcGIS Pro v2.6.3 and ArcGIS Online. It doesn't matter much to us whether the data is actually stored in UTC or not, but it matters that everyone working on this data see the same event occurring at the same hour, regardless of whether they view it via Pro or via AGOL. However, when Pro users then interact with those feature services in Pro, time is displayed in the local time similarly, if Pro users add features, those features' time attributes are added in local time and so display the "wrong" time in AGOL.Īs we are trying to use AGOL + Pro for event management, the four/five hour difference between UTC (displayed on AGOL) and Eastern Time (displayed in Pro) is a potential cause for major confusion. ![]() This time zone is in use during standard time in: Europe, Africa, North America, Antarctica. It is not feasible for them to publish these feature services from Pro or ArcMap (which I understand would allow them to associate the local time zone with these feature services). Greenwich Mean Time (GMT) has no offset from Coordinated Universal Time (UTC). These AGOL-only users sometimes create new hosted feature services with time fields. Therefore, by using it you can find an answer to. The use case that prompts this request is as follows: an organization has some users with Pro, and many more users who only use ArcGIS Online. It is a unique online tool to help our users convert UTC time into the current time in a certain time zone. If this older idea cannot be implemented: Option to not use UTC time offset in ArcGIS OnlineĬould we instead have the option to set ArcGIS Pro to display time in UTC, rather than in the local time zone of the machine it is running on? ![]()
