Are your tank gauges setup to automatically adjust for Daylight Savings Time?

Daylight Saving Time (DST) is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. The typical implementation of DST is to set clocks forward by one hour in the spring and set clocks back by one hour in autumn to return to standard time.

In the United States, Daylight Savings Time begins each year on the 2nd Sunday in March, when clocks are set forward by 1 hour. They are turned back again to standard time on the 1st Sunday in November as DST ends.¹

For a fueling site or convenience store there is a need to ensure that the data that is generated through their automatic tank gauge is being recorded at the correct local time so that various point of sales inputs can be reconciled with fuel levels. If set correctly the TLS-450PLUS and TLS-350 Automatic Tank Gauges can automatically adjust for daylight savings, maintaining the correct time stamp on all records and minimizing confusion.

Manage time settings on a TLS-450PLUS Automatic Tank Gauge

This quick tutorial shows how to set the date and time settings on the TLS-450PLUS Automatic Tank Gauge. These settings are used upon setup of the tank gauge, or can be used after a power outage or to update after a time change.

On the TLS-450PLUS and TLS4i/c consoles you do not specifically program Daylight Savings Time. The console has this functionality built into the time zone selection as well as updating directly through Network Time Protocol (NTP).

Setting the time on the TLS-450PLUS Console:

Follow the navigation to the Date and Time Settings. Select Menu > Setup > Date and Time.
Click in the Current Date field and a popup calendar appears, select the current date.
Click on the Current Time pull down fields to set the time.
Click on Time Zone and select the local time zone.
Enable Network Time Protocol (NTP), enter in your NTP server, test your connection, select check to enable.

(Note: You will see an error regarding the Time Zone settings. NTP bypasses the manual Time Zone settings but we recommend Time Zone is still used in case of lost connection.)
