TWAIN Capability: CAP_TIMEDATE

CAP_TIMEDATE

Description

The date and time the image was acquired.

Note: CAP_TIMEDATE does not return the exact time the image was acquired; rather, it returns the closest available approximation of the time the physical phenomena represented by the image was recorded. If the application needs the exact time of acquisition, the application should generate that value itself during the image acquisition procedure.

Stored in the form “YYYY/MM/DD HH:mm:SS.sss” where YYYY is the year, MM is the numerical month, DD is the numerical day, HH is the hour, mm is the minute, SS is the second, and sss is the millisecond.

This capability must be negotiated during State 7 before the call to the DG_CONTROL / DAT_PENDINGXFERS / MSG_ENDXFER triplet. It must also be listed in the CAP_EXTENDEDCAPS capability by the data source.

This is a read only capability.
