TOD Clock the same as the BIOS clock in PCs 3267
Speaking in terms of Mainframes, What is "TRUE UTC" mean?
Joel C. Ewing 360 clock was full word at location 80 in storage. low-end 360s tic'ed about at approx. 3mills. high-end 360s had high-resolution timer feature that tic approx. 13micros. the period...
1. What does this mean??? I am still lost like crazy here...When they speak in terms of setting the times as "TRUE UTC", do they mean the Hardware clock (TOD) is set to UTC and the Displayed time (the desktop clock) is set to UTC also??
2. What is the proper setting of the time in Mainframes and applications running on it? Does the TOD clock have to be set in UTC and also the actual DISPLAYED time on the DESKTOP also have to be set as UTC? Or, ONLY the Hardware clock (TOD) has to be set as UTC and the applications will log time as LOCAL TIME according to the offset?? In other words, do all applications running on the mainframes have to log their times as LOCAL time according to the offset from the TOD clock (which is set to UTC)?? Or, the applications are logged as UTC also??
Also, what is actually a TOD Clock? Is it the same as running the Real Time Clock or the CMOS clock on home standard PCs?? Is the same as that?
Thanks in advance!
