Configuring the Time Displays
The ptf 3207A has a number of different time displays that are selected via the main status screen.
Time can be displayed in either UTC, GPS or LOCAL time in 12 hour or 24 hour format, with a local time
zone offset, and with daylight savings time set to on or off.
• UTC (Coordinated Universal Time) differs from GPS Time by the addition of leap-second
corrections to compensate for variations in the earth’s rotation.
• GPS time is derived directly from the GPS constellation and doesn’t contain any leap-second
adjustments or other GPS-to-UTC corrections.
• Standard/Local Time is UTC plus a time zone offset. For example, Eastern Standard Time is UTC
minus 5 hours, if the daylight savings parameter is on and daylight savings is in effect, Local
Time is adjusted by adding an additional 1hour, i.e. EDT is UTC minus 4 hours.
Use the following menu items to configure how the ptf 3207A displays time.
