Hi, I am creating a GUI in matlab. I have a button and the time when I press the button is recorded. I manage to do that using clock. However, is there any way the start of the time is from 0s? Thanks.

Please edit the question and add much more details. "Using clock" does not explain clearly, what you are doing, therefore I cannot guess what the problem is.

Here are two simple ways to start a timer that counts from zero:
  • Use tic and toc to do the timing.
  • Use now, save the start time, and subtract this from all subsequent time values.

Hi mira
you can also use command "clock" as follows:
Start_Time = clock
it gives you the accurate time as following matrix
[year month day hour minute seconds]

Hi Mahdiyar, I am already using the command just like you say,but the thing is how I want to save the start time. This because the first pressed button already need to save the time.so I have to minus the time of first press button with the start time. Hope you understand what I mean.
