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 > environment variable, but I am not succesfull with it right now. It would be fine to ble able to set CreationDate. Otherwise, having a ModDate prior to CreationDate gives a weird impression.

Otherwise, having a > ModDate prior to CreationDate gives a weird impression. 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.

It would be great that current timezone doesn’t overwrite the specified one.
