3.2.4.3 DST and UTC, GMT
Neither UTC, nor GMT ever change to Daylight Savings Time (DST). However, some of the
countries that use GMT switch to a different time zone offset during their DST period. The
United Kingdom is not on GMT all year, but uses British Summer Time (BST), which is one hour
ahead of GMT, during the summer months.
Additional information about regional time zones and DST can be found on the following web
sites: http://www.worldtimeserver.com/,

3.3 Managing References
3.3.1 Input Reference Priorities
SecureSync can be synchronized to different time and frequency sources that are referred to as
Input References, or just References.
References can be a GNSS receiver, or other sources such as NTP, PTP, IRIG, ASCII or
HAVEQUICK time codes delivered into your SecureSync unit via dedicated (mostly optional)
inputs. It is also possible to enter a system time manually, which SecureSync then can syn
chronize to.
Should you be installing new option cards, you will need to either manually setup the new
card in the Reference Priority Table, or use the Restore Factory Defaults option in the Reference Pri
ority Actions panel, in order to update the table with the new reference information.
