I am attempting to publish a time enabled Map Image Layer into Portal for ArcGIS from ArcGIS Pro. I am referencing data published in an SDE. It publishes fine, and the resulting layer can be added to a Web Map with the time slider immediately available. When I look at the attributes of the service, the times have been adjusted plus one hour. Why does this happen and how can I fix it?
Your browser is converting the time values to UTC, I believe. Take a look at a few of these links as they may provide some guidance:
The general idea is that the data is stored in local time, but the browser is converting to UTC so you'll see that discrepancy.
Hi again Jonathan,
Through one of those links, I quickly realized that I needed to define the time zone (and daylight savings adjustment) for the data layer within ArcGIS Pro before publishing it as a Web Layer. I just have to make sure that I am applying daylight savings for the given dataset if required - AND - make sure that no datasets span through a transition into or out of daylight savings time! This fixes everything.
Thank you for the help!
