Changing time scale from second to milisecond

Hello everyone, i have a time range [0,3600] and there are some random data generated in 1 hour time scale, but i can only put data in a file in a second time scale, i want to change it to milisecond time scale, please can you help me? Thank you.

What do you mean by "put the data in a file"? The values do not contain any information about the scale.

Perhaps you want to use interp1 to interpolate the values?

i m sorry for the put the data answer, i mean to export values from a graph which shows the time axis and packet size axis and i want to export values in a lets say excel files with the corresponding time , but in my case i have just the seconds from 1,2,3.. 3600 but i want something 0,0.1...3600 and its corresponding values if there is packet generated at that time
