It is the following output nothing to be interpreted from it:

_time Average Unique Guest MACs
0NaN-NaN-NaN NaN:NaN:NaN 126
0NaN-NaN-NaN NaN:NaN:NaN 132
0NaN-NaN-NaN NaN:NaN:NaN 107
0NaN-NaN-NaN NaN:NaN:NaN 81
0NaN-NaN-NaN NaN:NaN:NaN 66
0NaN-NaN-NaN NaN:NaN:NaN 72
0NaN-NaN-NaN NaN:NaN:NaN 85
0NaN-NaN-NaN NaN:NaN:NaN 89
0NaN-NaN-NaN NaN:NaN:NaN 94
0NaN-NaN-NaN NaN:NaN:N

Try updated answer. _time is a special field and accepts only epoch time value.

Just add following to end of your search

Your search  | fieldformat _time=strftime(_time,"%m/%d/%Y")

Updated answer

Your search | eval Time=strftime(_time,"%m/%d/%Y") | table Time, "Average Unique Guest MACs"
