What are the possible ways to generate a random time series?

I require generating random times to test the computation. However, I got totally different results when I repeated my experiment for 1000 and, 10000 random time values. Here is the script that I used to generate random times.
NUMBER_RANDOM_TIMES = 10000;
SECONDS_PER_DAY = 24*60*60;
START_DATE = '2015-07-01';
END_DATE = '2021-12-31';
startDateNum = datenum(START_DATE,'yyyy-mm-dd');
endDateNum = datenum(END_DATE, 'yyyy-mm-dd');
dayRange = endDateNum - startDateNum;
secondsRange = SECONDS_PER_DAY*dayRange;
randomNumberOfSeconds = randi(secondsRange,NUMBER_RANDOM_TIMES,1);
randomDatenums = startDateNum + randomNumberOfSeconds/SECONDS_PER_DAY;
AA = datevec(randomDatenums);
I think maybe the random times generated by this method are biased. May someone share their thoughts and suggest other possible ways to generate random time's bounded between the start and end dates.

As per my understanding of the question when generating random numbers, the results can vary each time you run the experiment due to the nature of the random number generation algorithm.
The difference in results between 1000 and 10000 random time values could be due to the larger sample size in the latter case.
You can further refer to the following answer and documentation for a better understanding:

I hope the above information helps resolve your query.
