What does the date in the upper right-hand corner of a GenBank record mean?
The date in the upper right-hand corner of a GenBank record, to the far right on the LOCUS line, is the date of last modification. In some cases, it might correspond to the first release date into GenBank or when the record was last updated, but there is no way to tell simply from the data in the record. See corresponding FAQ 4. See the sample GenBank record for field descriptions.
