A minute, maybe 2. Variance on 60 second blocks isn't terrible, so I haven't seen a notably high block time yet.
First thing to check would be monerochain.info to see if it's been mined, just search for the transaction ID. If it is, then make sure you "refresh" the other wallet, and make sure you're caught up and in-sync with the network.
So my transfer still hasn't showed on the receiving computer but on the sender I have 2 balances. First a "balance" and then an "unlocked balance" which corresponds to the original balance minus the sum I sent. What's going on here? Appreciate the help.
Usually this suggests sending with an obsolete version of the client that uses too low a fee.
The solution in that case is to get the new software, restore your wallet using the keys file, and then resend.
Really appreciate all the help here but this is proving harder than I thought..
I re-downloaded Monero and installed a new version, synched the database and tried sending the transaction again. This time it worked but something strange happened. The 0.01 Monero I sent went through but there is also a pink transaction with the same transaction ID which is for 7 Moneros which has been deducted from the "unlocked balance". So to summarize my test send of 0.01 Moneros worked but an additional 7 Moneros (which I didn't send) seems to be stuck?
