Requires the TickSize amendment.
When an Offer is placed into an order book, its exchange rate is truncated based on the TickSize values set by the issuers of the currencies involved in the Offer. When a trader offers to exchange XRP and an issued currency, the TickSize from the issuer of the currency applies. When a trader offers to exchange two issued currencies, the offer uses the smaller TickSize value (that is, the one with fewer significant digits). If neither currency has a TickSize set, the default behavior applies.
The TickSize value truncates the number of significant digits in the exchange rate of an offer when it gets placed in an order book. Issuers can set TickSize to an integer from 3 to 15 using an AccountSet transaction. The exchange rate is represented as a number of significant digits plus an exponent; the TickSize does not affect the exponent. This allows the Ripple Consensus Ledger to represent exchange rates between assets that value greatly in absolute amounts (for example, a hyperinflated currency compared to a rare commodity). The lower the TickSize an issuer sets, the larger the increment traders must offer to be considered a higher exchange rate than the existing Offers.

Since transactions can take time to propagate and confirm, the timestamp of a ledger is used to determine offer validity. An offer only expires when its Expiration time is before the most-recently validated ledger. In other words, an offer with an Expiration field is still considered "active" if its expiration time is later than the timestamp of the most-recently validated ledger, regardless of what your local clock says.
