Not just slashed zeroes/ohs

[Martin Bishop]

Not to forget the practice, found in places where clock(s) may be set to Zulu (as in UTC timezone), of indicating the datum by a Z with a vertical bar / slash through it - often below the 12 and about 30% of the size of the clock face, or centred and somewhat larger.  Horizontal and no bar options may well also be found in the wild; which may have spread into the positioning, network management and timing communities ?

Having gone through many mathematics courses it was common to also place a slash on the letter Z to distinguish it from the numeral 2. Also for persons from Europe where they slashed the numeral 7 to distinguish it from a numeral 1 that commonly had an initial small upward stroke at the top when hand written.
