That's a Korn shellism I believe; in Bash the roughly equivalent builtin is type -- I think that's in POSIX too?

TIME(1) BSD General Commands Manual TIME(1)
NAME
time -- time command execution
SYNOPSIS
time [-lp] utility
DESCRIPTION
The time utility executes and times utility. After the utility finishes, time writes the total time elapsed, the time consumed by system
overhead, and the time used to execute utility to the standard error stream. Times are reported in seconds.
Available options:
-l The contents of the rusage structure are printed.
-p The output is formatted as specified by IEEE Std 1003.2-1992 (``POSIX.2'').
Some shells may provide a builtin time command which is similar or identical to this utility. Consult the builtin(1) manual page.
DIAGNOSTICS
The time utility shall exit with one of the following values:
1-125 An error occurred in the time utility.
126 The utility was found but could not be invoked.
127 The utility could not be found.
Otherwise, the exit status of time shall be that of utility.
SEE ALSO
builtin(1), csh(1), getrusage(2)
FILES
/usr/include/sys/resource.h
STANDARDS
The time utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').
BUGS
The granularity of seconds on microprocessors is crude and can result in times being reported for CPU usage which are too large by a second.
