F11 – Time Output Format
Use function F11 to review or change the format of the time output string used in F8 and F9. The as-

The default format for
F8 – Continuous Time Once-per-Second is:
DDD:HH:MM:SSQ
Note:
F8 does not display milliseconds, regardless of the format defined in F11.
The default format for F9 – Time On Request is:
DDD:HH:MM:SS.mmmQ
where:
The time quality character, “Q”, is one of the following characters:
See “F5 – Time-Quality Setup” on page 39 and “F13 – Time Error” on page 48 for more information.

the first character after the “F11” is a blank separator; it is not part of the format string.
