OK, but it was not a Windows question (particularly as we already
know from Tomek that that step may be omitted on Windows without
any obvious harm).  It is a more general question, applicable to
any operating system.  Q1 :  When TAR creates a file, does it set
"last modified" to "time created", as it has not yet been modified.
And Q2 :  If so, why is it then necessary to adjust "last modified"
as a separate step ?
