Telegraph pole (still used for telephone/power poles in some parts)
Carbon Copy
Blu Tac (which is now every other colour)
'Rewinding' a file on a digital recorder

I think you have found the closest identification!
"TimeStamp" is used in computer operations of all types and that is yet another (at one time an actual stamp with ink was used; as with a timeclock).
For some reason I am fascinated by these anamolies in our language.
