Talk:Wall-clock time

CPU time in parallel computing
The article should incorporate the information that it is possible for wall clock time to be less than CPU time, namely when doing parallel computation on more than one CPU. Eriatarka (talk) 14:09, 6 March 2009 (UTC)

Data processing & time differences
Should this artical also explain the time differences in a data processing context? A distinction is sometimes made between the time when the processing is actually performed (the Wall clock time ) versus when it should be done. Example: Each day a report must be made about orders completed the previous day. Due to a technical problem this was not done for several days. Later the the missing reports need to be generated. At that time the report generation will run as if it was a few days earlier - whereas the actual (wall clock time) time will be later. In particular, this applies to testing setups of such jobs. 193.191.180.231 (talk) 10:00, 10 August 2011 (UTC)

Delay extension
I often see wall time used to describe an entire business process, not just the computer part. As such it also includes delays incurred by the users themselves. The current article talks about programmed delays, and contrary to the variation described which excludes programmed delay, my experience includes user-delays. E.g.
 * 8 hour business time/day vs 24 hour wall clock time/day
 * user breaks
 * waits because the user-operator needs to obtain information from others. — Preceding unsigned comment added by 78.23.192.33 (talk) 21:17, 4 January 2013 (UTC)
