Dear list,

I have the following sample:

  \setupinteraction[state=start,
    date={02.02.2022}]
  \starttext
  This document is from 02.02.2020 at 12:00:21.
  \stoptext

Which is the right way to get PDF dates working with \setupinteraction?

Many thanks for your help,

Pablo

According to lpdf-mis.lmt about the "date" parameter:

    -- users should enter the date in 2010-01-19T23:27:50+01:00 format
    -- and if not provided that way we use the creation time instead

I can get this format also with `date --iso-8601=seconds` or the shorter
`date -Iseconds`.

So this works:


    \setupinteraction[state=start,
      date={2022-02-02T12:00:21+02:00}]
    \starttext
    This document is from 02.02.2020 at 12:00:21.
    \stoptext

This parameter sets the "ModDate" is that what you are after?

Seems that "CreationDate" could be set by the SOURCE_DATE_EPOCH
environment variable, but I am not succesfull with it right now.

Hi Michal,

many thanks for your fast reply.

I would like to import both metadata values (CreationDate and ModDate)
from another file (such as https://pdf.ousia.tk/metadata.pdf).

Besides from the fact that LMTX doesn’t work with this (only MkIV does
[already reported]), isn’t no simpler way to get ISO 8601 formatting
from doc.Info.ModDate than the following one?

  \starttext
  \startluacode
  function document.transfer_metadata(name)
    local main_doc = lpdf.epdf.load(name)
    context.setupinteraction{ title = main_doc.Info.Title }
    context.setupinteraction{ date =  main_doc.Info.ModDate:sub(3,6) ..
    "-" .. main_doc.Info.ModDate:sub(7,8) .. "-" ..
    main_doc.Info.ModDate:sub(9,10) .. "T" ..
    main_doc.Info.ModDate:sub(11,12) .. ":" ..
    main_doc.Info.ModDate:sub(13,14) .. ":" ..
    main_doc.Info.ModDate:sub(15,22):gsub("'", ":") }
    context(main_doc.Info.Title .. "\\par")
    lpdf.epdf.unload(name)
  end
  \stopluacode
  \unexpanded\def\TransferMetadata#1%
    {\ctxlua{document.transfer_metadata("#1")}}
  \startTEXpage[offset=1em, align=center]
  \TransferMetadata{metadata.pdf}
  \stopTEXpage
  \stoptext

> Seems that "CreationDate" could be set by the SOURCE_DATE_EPOCH

It would be fine to ble able to set CreationDate. Otherwise, having a
ModDate prior to CreationDate gives a weird impression.

Many thanks for your help,

Pablo

I don't know how official these interfaces are. But you can try adapting
the following to your use case.

    \setupinteraction[state=start]
    
    %\luacode{lpdf.settime("2020-02-02 12:00")}
    %\luacode{lpdf.settime(1580641221)}
    
    \startluacode
    
    local Y, M, D, h, m, s, Zs, Zh, Zm = string.match("D:20200202120021+02'00'", "^D:(%d%d%d%d)(%d%d)(%d%d)(%d%d)(%d%d)(%d%d)([%+%-])(%d%d)%'(%d%d)%'$")
    
    local time = os.time{year=Y,month=M,day=D,hour=h,min=m,sec=s}
    lpdf.settime(time)
    \stopluacode
    
    \starttext
    This document is from 02.02.2020 at 12:00:21.
    \stoptext

The pattern doesn't catch all the PDF spec cases, but should match what
ConTeXt emits. The timezone info gets overwritten by current timezone
though.

Requires the below patch.

i'll fix it but also clean up the existing code a bit

(much has to do with omitting date and is for comparison reasons)

Many thanks for the fix. It would be great that current timezone doesn’t
overwrite the specified one.
