Re: [TCLCORE] Any objections to change "clock format -now" to "clock format now" ?

[Marc C. <cul...@gm...>]

If it were up to me I would make the time value argument to the clock
format command be optional with the default value being the current time in
seconds.  That would mean that the shortcut command would be:
% clock format -format "%Y-%m-%d"
which is a shorter shortcut than either the one using "now" or the one
using "-now".  If it had been up to me long ago I would probably have
replaced "-format" by "-pattern", given that the subcommand is named
"format".

But I am not objecting to using "now".
