Appendix: Time Settings

Preferably a LTC-signal (Linear Timecode) is used to synchronize time codes. If this is not possible,
other options are:



NTP sync (Network Time Protocol) to a NTP- server.



Free running (system uses an internal clock)

Setting up NTP:

Edit /system/objects/code/setdate



NTPSERVER: specify the NTP-server's IP-address



ZONE: specify time zone [see options below], the ZONE-setting determines offset relative to
CET/GMT.

To test settings, from Linux command line enter:
/system/objects/code]# setdate -ntp [enter]

If settings are incorrect, an error message will be displayed.

To ensure that time is regularly synced, edit /etc/crontab. Remove the "#" in front of the line:

#00 * * * * root /system/objects/code/setdate -ntp >/dev/null 2>&1

Result:

00 * * * * root /system/objects/code/setdate -ntp >/dev/null 2>&1
