this way or that way

[Pidginboy]

Your talk is scheduled between 11.00 and 11.15 a.m.; but due to unexpected changes, the order (sequence) of the scheduled speakers is likely to change. As a result, your slot may be either this way or that way by 10 minutes. ( Its meaning is that your slot may be either advanced or delayed by 10 minutes.) What is idiomatic way of saying what is bold form?

 

[Nymeria]

In casual speech, I would say that the slot may either be "moved up" or "pushed down" by 10 minutes.

I second Nymeria. In AE though, we would say "pushed back" instead of "pushed down".
