Time_Synchronization_Recipients (Read-Writable). This list of recipients will receive
TimeSynchronization requests on time synchronization events. A recipients is either
specified by its device ID (the object ID of its Device object), or its BACnet address. By
default, this list is empty.
UTC_Time_Synchronization_Recipients (Read-Writable). This list of recipients will
receive UTCTimeSynchronization requests on time synchronization events. A recipients is
either specified by its device ID (the object ID of its Device object), or its BACnet address.
By default, this list is empty.
Time_Synchronization_Interval (Read-Writable). The Unsigned value of this property
specified the time interval in minutes in which periodic time synchronization events are
created. If set to zero, no periodic time synchronization events are generated.
The actual clock time at which periodic time synchronization events are generated is
determined by the properties Time_Synchronization_Interval, Align_Interval, and
Interval_Offset; Table 16 outlines how these properties interact..

Table 16: Periodic time synchronization events are parameterized by the properties
Time_Synchronization_Interval, Align_Interval, and Interval_Offset.
*
Current hour or minute refers to the hour or minute at which one of the properties
Time_Synchronization_Interval, Align_Interval, and Interval_Offset is set, e.g., the hour or minute
the device completes the boot process or one of these properties is modified via BACnet services.
By default, the value of Time_Synchronization_Interval is 1440 (minutes), i.e., one day.
Align_Intervals (Read-Writable). The Boolean value of this property determines whether
or not periodic time synchronization events shall be anchored at the start of a day or hour
(TRUE) or not (FALSE), provided Time_Synchronization_Interval is a multiple of a day
(1440 minutes) or hour (60 minutes). Table 16 details on how this property influences
generating periodic time synchronization events. The default value of this property is
TRUE.
Interval_Offset (Read-Writable). While Time_Synchronization_Interval specifies the
period in which time synchronization events are generated, the Unsigned value of this
property determines the point of time in minutes within this interval at which the time
synchronization event is actually triggered. If the value of Interval_Offset is larger than the
value of Time_Synchronization_Interval, the remainder of Interval_Offset divided by
Time_Synchronization_Interval is used. The default value of this property is 0.
