Printing the float is not having any safety:

sprintf(smicrosec,"%f",tsecmicro);

Variable smicrosec has the size 18, I assume you wanted to have 10digits . 6digits, but then enforce it because %f can have exponential representation, where the lenght can differ from system to system. Use:

sprintf(smicrosec,"%17.6f",tsecmicro);

Push this as an extra patch to your branch to show in pull request. Also, add the documentation and the PR will be merged.
