Here's an example:

% a table
T = table([1;2;3],[4;5;6],'VariableNames',{'Time','x'})

T = 3×2 table
    Time    x
    ____    _

     1      4
     2      5
     3      6

% Time column is not duration or datetime
class(T.Time)

ans = 'double'

% try to convert T into a timetable
try
    T = table2timetable(T) % error
catch e
    disp(sprintf('Error: %s',e.message))
end

Error: Input table must contain datetime or duration vector for row times.

% convert T.Time to durations in seconds
T.Time = seconds(T.Time)

T = 3×2 table
    Time     x
    _____    _

    1 sec    4
    2 sec    5
    3 sec    6

% now Time is duration
class(T.Time)

ans = 'duration'

% and T can be converted into a timetable
T = table2timetable(T)

T = 3×1 timetable
    Time     x
    _____    _

    1 sec    4
    2 sec    5
    3 sec    6
