Note: This is not tested and might have syntax errors.
I believe there are few changes needed. This will definitely get into a infinite loop due to highlighted lines Smilie

May be you have to set a variable for the next second Smilie

NAME
time - time a command SYNOPSIS
command utility [argument ...] DESCRIPTION
When a specified command or utility completes execution, prints the elapsed time during the command or utility, the time spent in the sys- tem, and the time spent executing the command or utility. Times are reported in seconds. Execution time can depend on the performance of the memory in which the program is running. The times are printed to standard error. Note that the shell also has a keyword that times an entire pipeline if used anywhere in the pipeline. This action is different than the command which times a particular command if used in a pipeline. Options recognizes the following options: command The command to be executed and timed. Writes the timing statistics to standard error. utility The name of a utility to be invoked and timed. If the utility operand names any of the shell special built-in utilities, the time results are undefined. See csh(1) and ksh(1) for information about special built-in utilities. argument Any string that is an argument to the utility. SEE ALSO
csh(1), ksh(1), sh(1), timex(1), times(2). STANDARDS CONFORMANCE
