Had the same thing some days ago. It's a bug most likely caused by daylight saving times. I've posted about it here within the last 14 days.
It's actually -9 minutes what you're seeing (but displayed as +9) and counting to -60. I'm 99% sure that you'll have the money back in 51 minutes (counted from your 9 minutes)
I've seen the same thing at various times, but with no apparent connection to daylight savings and not as neat as exactly an hour.
It's the same display bug where negative numbers display as positive, but I'm pretty sure it can also happen in the space of time between when the swap was (strictly speaking) supposed to end, and when a scheduled "update/check all the swaps" batch job runs to actually close it.
