1608 Daylight saving time indication
Created: 30 Dec 2017
Status: Future Improvement
Clause: none yet
Category: Issue for edition 2 of this part
To support legacy installations that operate with IRIG-B, it may be necessary to convert time synchronization from PTP to IRIG-B. To this effect, IRIG-B needs an indication that daylight saving time is in effect. This information is carried by the PTP ALTERNATE_TIME_OFFSET_INDICATOR (IEEE 1588 §16.3)
Grandmasters that support the ALTERNATE_TIME_OFFSET_INDICATOR (IEEE 1588 §16,3) should indicate the supported time zone in the displayName according to the abbreviation in https://www.timeanddate.com/time/zones/.
