Time zone information for a date field in a web feature layer is displayed in the ToolTip for the field header as well as any calendar control when editing those values. For instance, the ROUND function would round a number to a given number of decimals in a file geodatabase: Refer to the documentation of your DBMS for a list of supported numeric functions.
