Date and Time Settings
Use the Date and Time Settings page to set the Coordinated Universal Time (UTC) and/or system
time and date on a device, or set the offset from UTC for the Digi device's system time.
Set the date and time
To set the date and time, click the
Set
button to configure the hours, minutes, seconds, month, day,
and year on the device.
If offset is set to 00:00, the device's system time and UTC are the same. Setting time and date with an
offset of 00:00 results in both UTC and system time being set to the specified value. If offset is not
00:00, setting time sets the system time to the specified value and UTC is adjusted accordingly.
Offset from UTC
Specifies the offset from UTC for this device. Offset can range from -12 hours to 14 hours. Very rarely,
a time zone can also have an offset in minutes (15, 30, or 45). You can use this value to modify the time
and date (generally expected to be UTC) to compensate for time zones and daylight savings time.
Wikipedia provides a list of time zone offsets at:
https://en.wikipedia.org/wiki/Lists_of_time_zones
On a device with no real-time clock (RTC) and no configured time source, time and date are
completely local to the device and have limited usefulness since they are not persistent over
reboots/power-cycles.
On a device with a real-time clock and no configured clock source, time and date are also local to the
device but they are meaningful because they are persistent. The offset option could be useful in
adjusting for daylight savings time. Setting the date and time to standard time and setting offset to 1
whenever daylight savings time is in effect would serve that purpose.
On a device with a configured clock source, time and date received from a clock source is expected to
be UTC. For users with several devices in different time zones, keeping offset=00:00 might be useful
for comparing logs or traces from different devices, since all would be using UTC.
Time source settings
The time source settings configure access to up to five external time sources that you can use to set
and maintain time on the device.
n
Type
: Specifies the type of time source for this entry.
l
sntp server
: The device uses its SNTP client to poll the NTP/SNTP server, specified by the
FQDN, for time.
l
cellular
: The device polls the cellular service for time.
n
Interval
: Specifies the interval in seconds between polls of a time source. Interval can range
from 1 second to 31536000 seconds. If more than one time source is specified, time sources
with shorter intervals have greater influence on the device's time than do sources with longer
intervals.
n
FQDN
: Specifies the fully-qualified domain name or IP address for the time source. Use FQDN
only if the time source is SNTP.
The only time source that is guaranteed to be present on all products at all times is the system clock.
It counts uptime and displays system time as the Unix Epoch (00:00:00 on January 1, 1970) plus
uptime. Any source that is not the system clock is considered an external source. This includes the
RTC.
Devices which have an RTC but have no external time sources configured will display system time as
the Unix Epoch plus the time since power was initially applied to the device until system time is set
manually. You can manually set system time via the CLI, Web UI, and so on. Once system time is set
