bar lines shift when using proportional notation

[Adrian Kleinlosen]

Hi LilyPonders,

I would like to notate a piece proportionally. To do this, I have created (with a little help) a markup command that I can use to place time signatures above the bar lines. But as soon as I do this, they move to the left, whereas the bar lines are in the right place if I don't use the markup. (See the code below.) Can anyone tell me why this is and how I can counteract it?

Cheers, 

Adrian
