Current system time as a Timestamp
1 215 views (last 30 days)
I want to get the current system time in microseconds and share this timestamp with other computer via UDP. How to do that. fprintf('This message is sent at time %f', time) Is something like above possible in matlab? Please help me with this.

fprintf('This message is sent at time %s\n', datestr(now,'HH:MM:SS.FFF'))

A timestamp with a precision of microseconds is not meaningful, when the command to obtain the timestamp needs more than a microsecond. Then it is not exactly defined if the stamp belongs to the time before or after the command.

This is an old post the got reopened. I feel compelled to say that in anything like recent versions of MATLAB, datetime('now') is much preferred over now.
On Windows, the clock function and datetime('now') both return a system time rounded to milliseconds. On Linux or Mac, it's rounded to microseconds. Whether or not either of those is actually accurate or not depends entirely on your system though.
