That won't work because time is a special shell keyword, and as such
only recognized when it's the first word on the command line. The same
is true of all shell syntax-driving keywords such as "case", "for",
"while", etc.  (But not for simple built-in commands, which can appear
anywhere the name of an actual command program on disk can).

That just means that the Linux system has the standalone time(1)
command installed.  As it happens, my Cygwin install also has a
/bin/time.

You can just move the assignment to after the 'time':

eval time foo=bar env | grep foo

real    0m0.120s
user    0m0.000s
sys     0m0.078s
foo=bar
