It is still not fully compatible with an unchanged \time command, but
perhaps it helps nonetheless. The only required change is this:
\time must be replaced by \customtime
Once that is done in the music, it depends only on the \layout block
whether you have dashed or solid barlines and before a time signature
change, you always have a solid one.

\version "2.17.9"

\layout {
  \override Score.BarLine #'glyph-name = #"!"
}

customtime =
#(define-music-function
     (parser location frac) (fraction?)
   #{
       \once \override Score.BarLine #'glyph-name = #"|"
       \time #frac
   #})

{ % example
  a a a a
  \customtime 3/4
  b b b
  b2.
}
