$ zsh -c 'A=1 time'
zsh:1: parse error near `time'
Compared to:
$ zsh -c 'A=1; time'
shell 0.00s user 0.01s system 295% cpu 0.003 total
children 0.00s user 0.00s system 0% cpu 0.003 total
This seems to be specific to the time builtin when prepended with a env var
assignment, echo works properly. Could not find a ticket related to this on
sourceforge, my apologies if it has been reported before.
zsh 5.7.1 (x86_64-apple-darwin17.7.0)
Cheers,
Emil

It's a little obscure, but this isn't actually a bug. If you look in
the appropriate manual section, you'll see that "time" is defined as a
"complex command" which takes a pipeline as an argument. So assignments
etc. come after it (and potentially a number of "|"s with their own
command lines that may include assignemnets).
To put it another way, the parse error here is roughly similar to the
failure you get here:
A=1 { echo; }
In both cases, no command line can appear before the complex command.
