1693.0. "Date&Time in distibuted environment ?" by TENERE::BOSSARD () Wed Oct 23 1991 06:02

Hello,

I would be glad to receive some inputs regarding the 2 following questions sent
by one of our potential customers :

	1-How time&date will be managed in a distributed environment ?

	2-How synchronization of systems will be performed ?

Thank's in advance for any contribution,

	JJ

1693.1	DTS and GPS timeing is a good option	CLARID::PATEL	We'll get it right on the night	`Wed Oct 23 1991 10:27`	9
	Re .0 Not specifically to do with MCC, this question has been raised in several other cases... Use of Distributed Timing services is one option, and the use of GPS (Geometric Positioning System) for a accurate time source to set DTS is a good idea.... Amrit
1693.2	DECdts works well; recommended for DECdns	CUJO::HILL	Dan Hill-Net.Mgt.-Customer Resident	`Fri Oct 25 1991 00:38`	9
	Additionally, when using DECdns (distributed name service) on multiple nodes, you must use DECdts (distributed time service) to ensure that all nodes are synchronized properly. System times must be within 5 minutes of each other when DECdns is used. We are using both DECdts to synchonize nodes in our 14-node cluster. We can easily stay within one second of each other. -Dan
