In the current implementation and according to the WAT specification (https://webarchive.jira.com/wiki/display/Iresearch/Web+Archive+Metadata+File+Specification), WARC-Date is a 14-digit timestamp that represents the instant of data capture of the primary content.
The WARC ISO standard states WARC-Date is mandatory and corresponds to:
"A 14-digit UTC timestamp formatted according to YYYY-MM-DDThh:mm:ssZ, described in the W3C profile of ISO8601 [W3CDTF]. The timestamp shall represent the instant that data capture for record creation began. Multiple records written as part of a single capture event (see section 5.7) shall use the same WARC-Date, even though the times of their writing will not be exactly synchronized."
WAT records are metadata records which can be created long after the data capture, and with different kind of processing tools. WARC-Date in all metadata records should be the WAT record generation date.
