[PATCH 1/3] programs/cmd: %time% should have 1/100s resolution.

[Francois Gouget]

Stub out the subsecond decimals.

GetTimeFormatEx() does not support formatting fractions of a second. So
just stub out that until there is a need for it. At least now echo
%time% can be used to see where a batch file spends its time.
