So does this provide our cheap-as-chips solution? Run an NTP client on the SEs and HMCs? ;-)
It would only do it at POR, and not help for the drift after that. In a former life we had PCs with 3270 coax cards as HMC (when the HMC was still 3270, as &deity designed it) and operator console. The scripts would set the clock during IPL of the LPAR. With regular IPLs that worked pretty well to avoid much drift. And I think the granularity of this is full seconds only, so it is still rather sloppy. If you read the books on the ETR, you'll see that this stuff really is more complicated than what you would build in your garage. That is if you need this to be fault tolerant etc. Rob ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
