Datetimes wrong in 'getdocinfo_pdftools()'

[trevorld]

• Seem to be overally precise presumably because {pdftools} is coercing them into an inappropriate datetime class like POSIXlt instead of datetimeoffset():

> library(grid)
> f <- tempfile(fileext = ".pdf")
pdf(f, onefile = TRUE)
grid.text("Page 1")
grid.newpage()
grid.text("Page 2")
invisible(dev.off())
> get_docinfo(f)[[1]] |> print()

[trevorld]

• Wait until https://github.com/trevorld/r-datetimeoffset/issues/42 to submit issue upstream so there is a possible concrete solution they could use

[trevorld]

• poppler API only returns time_t times (second since Epoch): https://poppler.freedesktop.org/api/cpp/classpoppler_1_1document.html
• Due to this limitation I don't think {pdftools} can "fix" this on their end...
