You are sharing a map image layer. You cannot specify the time zone as Unknown because the map has a time-aware layer or stand-alone table that has a time zone defined.
The first <value> parameter is either a layer or table.
The second <value> parameter refers to the name of the layer or stand-alone table.
Solutions
Do one of the following:
- Specify a time zone for the web layer. You may want to choose one that matches the time zone defined in the time-aware layer or stand-alone table.
Hover over the analyzer message. Click the Options button
that appears and click Set Time Zone. Under Date Fields, click the Time zone of the data drop-down arrow and choose the time zone in which the date values are stored. - Change the time properties defined in the layer or stand-alone table.
Hover over the analyzer message. Click the Options button
that appears and click Change Layer Time or Change Table Time. On the Layer Properties dialog box, on the Time tab, change Time Zone to <None>, or set Layer Time to No Time. For more information, see Set time properties on data.
