It may not be useful to "complete" short things but the descriptions can
be very useful. There's quite a few cases where this is done, e.g.:
  printf '%<tab>
  : ${(<tab>
  !!:<tab>

Stripping suffixes is easily forgotten when writing completion functions
and this was one such case. Patch below should fix this and make
it indicate the default of "days" when there is no time specifier.

With `unsetopt completeinword', you have the equivalent of moving the
cursor to the end of the word. *(m) is an invalid glob matching no
files. You might also want to consider using the _prefix completer which
ignores the entire suffix.

Are you using the _expand completer or the default expand-or-complete
widget to do expansion.

Braces are largely handled by internal C code: _prefix doesn't seem able
to help here. You can prevent the expansion with something like:
  zstyle -e ':completion:*::::' completer \
    'reply=( _oldlist _complete ); (( $#SUFFIX )) || reply[1]+=( _expand )'
