pdfTeX 3.14159265-2.6-1.40.17 (TeX Live 2016)
- changes:
- - if environment variable SOURCE_DATE_EPOCH is set, use its value for
- the CreationDate and ModDate values, and to seed the trailer /ID.
+ - if the environment variable SOURCE_DATE_EPOCH is set, use its value for
+ the PDF CreationDate and ModDate values, and to seed the trailer /ID.
This by itself should suffice to create reproducible PDFs. The
- other changes support more granular output tweaks along the same lines.
+ new primitives below support more granular output tweaks with the
+ same intent.
+ - if the environment variable SOURCE_DATE_EPOCH_TEX_PRIMITIVES is set
+ to 1, the \year, \day, and \time primitives are also initialized
+ from the SOURCE_DATE_EPOCH value, instead of the current time.
- new primitive \pdfinfoomitdate to omit CreationDate and ModDate keys.
- new primitive \pdftrailerid to set seed for the trailer /ID
