This time is calculated by the client when it downloads a unit. It is determined by adding the "begin" time to the expiration period, if this expiration data is sent as part of the work unit. The interval, which qd shows in parentheses after the date, is rounded to the nearest day, or to the nearest hour if it is less than two days. Genome units had no deadlines, nor do a few Folding units designated for machines which are either slow or only infrequently connected to the Internet. All other Folding units do, but not all work units have the expiration period fields filled in. The stored time is an epoch 2000 value, based on the local machine's clock.

There are actually two sorts of deadline associated with a work unit. The one reported here, which is the only one known to the client, is what the Stanford project summary web page calls the "Final Deadline", after which time the client may delete the unit and no credit will be given even if it is completed and returned. The other deadline, shown on the project summary as "Preferred", indicates when the unit will be considered late enough that the server might send another copy of it to someone else, which means that a unit returned after that time might have little scientific value.

NOTE that if the machine clock runs, or is set, forward to a time past the "due" date, the client might think the unit is past due, and delete it.
