can matlab handle data with microsecond precision and if not how to convert time to microseconds

I am working with data that needs to be in microseconds.

How to do that in Matlab.

Your question is quite general, so only a general answer is possible. Yes, MATLAB has multiple ways of using dates and times and data types, and microsecond precision is typically possible. See this page about dates and times in MATLAB, for example.

oh sorry for being less specific. I wanted to make it look easier. I am implementing PTP IEEE 1588 protocol in MATLAB and for that, i need the timestamps to be in microseconds . and how can i achieve that.

Are you using R2014b or later, or are you using a version before that?

can R2014b handle precision in microseconds? and how can i achieve this. Some Commands will be really helpful.

[Walter Roberson]

R2014b and later support datetime objects, which extend the precision with which times can be stored.

For dates close to the present, eps(now) returns about 1e-10; multiply that by 24*60*60 to find that the precision that times can be represented at present with serial date numbers is about 1E-5 seconds, or roughly the 10 microsecond range.

The new datetime objects have up to nanosecond resolution

This page about PTP in Simulink came up in a google search. Maybe it is a good place for you to start. (Disclaimer: I have no personal knowledge about PTP or its implementation.)
