Removing time change from previous line

[Alberto Simões]

Hello

Is there any way to remove the time signature that is shown in a 
previous line, when the time is changing?

Not sure if I made myself clear: when issuing a \time command, if it 
occurs at the end of the staff line, it is repeated at the end of the 
current staff, and in the beginning of the next. I would like to remove 
the one from the previous line.

In fact, not only the time, but also the key signature >:)

Thank you,
Alberto
