60 days from payment date is what Moniker first says, but when pressed, they indicate they may go beyond that timeframe, since credit card disputes can go way beyond 60 days; the reason PayPal, etc uses 6 months as a guideline for "holds".
Transferring out may not protect a buyer either in such an instance - Moniker has publicly stated they would attempt to convince the receiving registrar to transfer it back; undo the registrar-transfer.
A true escrow deals only with non-revocable, secured funds ... totally assumes the risk, if choosing to accept revocable funds.
Undoing transactions after closing is way outside the function of escrow ... and make no mistake, such actions can put both buyer and seller at risk.
For people who seek escrow of both the funds and domain, Sedo is a better choice ... key differences with Sedo is they will assume the risk with revocable funds, and also they are not a registrar and thus not in a position to "take" it back after closing even if they wanted to.
I harp on this topic whenever it comes up because the way Moniker implements escrow is bad for the domain market - people need to have confidence that when using an escrow service that when a transaction closes, it closes ... no undoing it, no taking it back, etc nonsense.
