Configuring the Time Service
Configuring the Time Service
iTX calculates all playout times on the basis that the Time Service delivers time in the
international standard, UTC. You need to configure the Time Service to ensure it meets this
requirement. You should do this by using the Time Service Configuration tool:
In configuring the Time Service, you specify the location of the time source. You also specify
whether or not the time source has any offset from UTC (either for a timezone difference or for
daylight saving); this enables the Time Service to convert the input, if necessary, to ensure its
output is in UTC.
The iTX services that require a time source have an in-built component called a time-service
client; the iTX Desktop also has this component. A client receives the UTC time from the Time
Service and passes it to its service or iTX Desktop. The client can adjust the time, for a timezone
or daylight saving, before it does this. Any adjustment is set in the Time Service configuration.
Because the iTX playout service TXPlay has its own configuration options for a timezone offset
and daylight-saving boundaries, we recommend you do not make such adjustments in the Time
Service. Instead, you should configure them for each playout channel on the Channel
Configuration pop-up layout. See "UTC Offset", page 144, and "Daylight Saving Time
Boundaries", page 144.
