SEMI E148: Specification for Time Synchronization and Definition of the TS-Clock Object
This standard provides a more comprehensive approach to time management than the basic Clock capability described in the SEMI E30 (GEM) standard. Describes a network time synchronization protocol, an SEMI E39 Clock object whose attributes can be updated via standard Stream 14 messages, and a super-accurate 32-byte time format with a time zone designator.
A number of our products support SEMI E148.
