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.
