4.4.6 Date and time
Click on "Date and Time" in the menu.
This menu enables initialisation of the date and time of the card in three different ways.
The date format is always of year/month/day type
Z Set manually: Enables initialisation of the date and time of the card, with the values entered in the Date and Time fields. This update is
made after clicking on the "Save" button .
Maximum drift is +/- 2 min./month
Z Synchronize with NTP server: Enables connection with a time server, either available on the company’s internal network or on the Web.
This server communicates GMT time. The IP address or hostname of the time server must be entered, and the time zone of your
geographic area must then be selected from the list. Connection is made with the server and the date and time are set after clicking on
the "Save" button. Time is updated every five hours, thus preventing any drift in the time. After two attempts, if the NTP server is not
accessible, the card shifts to manual mode.
The card uses the NTP protocol (UDP 123 port). The "firewall" must be set to transmit queries outside the intranet. No error message is
generated if the time server contact fails.
Note 1:
The even the card is used in a UPS supporting time-stamping, the card's time is automatically synchronized with that of the UPS.
Note 2:
After startup, if the card is in manual mode or if no NTP server was reached, the card initializes at 01/01/1970
