'time' does NOT work on a function in 'dash'.
Hi guys and gals...

I am writing a piece of code that is dash compliant and came across this error.
I have put it in the OSX section as that is what I am using.
I have no idea what the 'dash' version is but was installed about 6 months ago.

MBP, OSX 10.12.6, default terminal running dash on top of default bash.
Code:
#!/usr/local/bin/dash

delayme()
{
	echo "Sleep for 1 second."
	sleep 1
}

echo "Test the function."
delayme

echo "Test the timer."
time delayme

echo ""
echo "Test a real command."
time sleep 1

Result...
Code:
Last login: Mon Sep 11 19:10:20 on console
AMIGA:amiga~> cd Desktop/Code/Shell
AMIGA:amiga~/Desktop/Code/Shell> ./dash_function.sh
Test the function.
Sleep for 1 second.
Test the timer.
delayme: No such file or directory
        0.00 real         0.00 user         0.00 sys

Test a real command.
        1.00 real         0.00 user         0.00 sys
AMIGA:amiga~/Desktop/Code/Shell> _

I have no idea if this error also exists with Linux or other UNIX like flavours.
Does anyone know the reason why this error occurs using 'time' on the _function_ as the code works perfectly in 'bash'.
I can't find anything about it on the WWW.

TIA.
Bazza...
