Abstract
A process control and manufacturing information database client application is disclosed displaying received time-series data in an unambiguous manner when a displayed range of time-series data includes a DST transition for a designated time zone for displaying the data. A data acquisition interface obtains timestamped time-series data values for an observed parameter from the process control and manufacturing information database. The data values are requested/received/stored by the client application, for example, according to the UTC time standard. The client application renders the timestamped time-series data values as a series of points on a time-line graph. The time-line graph includes alphanumeric time labels specified in accordance with a designated time zone. The display function renders the time-line graph without disruptions over a time span containing a Daylight Savings Time (DST) transition for the designated time zone.
