time-stamp-start is a variable defined in `time-stamp.el'.
Its value is

"Time-stamp:[ 	]+\\\\?[\"<]+"

• This variable is safe as a file local variable if its value
  satisfies the predicate `stringp'.

Documentation:
Regexp after which the time stamp is written by M-x time-stamp.
See also the variables `time-stamp-end' and `time-stamp-line-limit'.

This value can also be set with the variable `time-stamp-pattern'.

Do not change `time-stamp-line-limit', `time-stamp-start',
`time-stamp-end', or `time-stamp-pattern' for yourself or you will be
incompatible with other people's files! If you must change them for some
application, do so in the local variables section of the time-stamped file
itself.
