TimeStamp timestamp

File modification time stamp. Specifies the date/time the image and/or data files attached to this catalog record were last modified.

If attribute::UseLastModified is set, the most recent of the catalog::TimeStamp and vignette::TimeStamp values of all materials and the vignette involved in the request is returned in the HTTP response as a last-modified header.

The actual file times of the image or data files attached to this catalog record are never used for this purpose.

The catalog::TimeStamp is also used for catalog-based cache validation (see attribute::CacheValidationPolicy).

Date/time value in Java™ format. It can be either the integer number of milliseconds since midnight, January 1, 1970 UTC/GMT, or a date/time string value with one of the following formats:

mm/ dd/ yyyy hh: mm: ss zzz

mm/ dd/ yyyy hh: mm: ss GMT offset

  • hh is in the range 0–23.
  • zzz is a three or four character time zone code such as ‘GMT’ or ‘PST’. Daylight Savings Time must be accounted for in the time zone code. For example, ‘PST’ for Pacific Standard Time, versus ‘PDT’ for Pacific Daylight Savings Time.
  • offset is a time zone offset in hours or hours:minutes, relative to GMT. For example, ‘PDT’ is equivalent to ‘GMT -7’.

All elements of string-formatted date/time values must be present. If the date/time value is not formatted correctly, it is ignored and the modification time of the catalog.ini file is used instead.
