Any method to insert timestamp in front of the trace command turned on
by set -x? We try to troubleshoot zsh startup time problem when
people sharing the common zsh startup across US and in India.
Timestamp will give us a clue which part take the longest and we
can then make proper adjustment.
Any help will be appreciated.

Yes, if you're using 3.1.6 or later. Just set PS4 using any of the usual
prompt expansion escapes, e.g.:
% PS4=': %D %T ; '
% set -x
% sleep 5; echo hello
: 01-04-15 12:43 ; sleep 5
: 01-04-15 12:43 ; echo hello
hello
If you need finer granularity, setopt promptsubst and use $SECONDS:
% setopt promptsubst
: 01-04-15 12:44 ; setopt promptsubst
% PS4=': %D %T {$SECONDS}; '
: 01-04-15 12:44 ; PS4=: %D %T {$SECONDS};
% sleep 5; echo hello
: 01-04-15 12:45 {261}; sleep 5
: 01-04-15 12:45 {266}; echo hello
hello
One-second granularity is the smallest you can get.
I chose the :...; format so that you can cut-and-paste the trace output
into another shell and the leading timestamps will be ignored.

not needed; just use %D{%Y-%m-%d %H:%M:%S}, which will give you
seconds.
