Unusual timezone offsets

[mazeckenrode]

I have two PDFs, an insurance policy renewal declaration and an invoice for that policy's upcoming renewal, which both have PDF Created & Modified timezone offsets that don't look right and result in tooltip/PDF software displays of created & modified times that don't make sense to me. For example, one PDF has the following (as exported to JSON):

Code Select Expand

"PDF:CreateDate": "2025:03:13 01:09:39+01:09",
"PDF:ModifyDate": "2025:03:13 01:09:39+01:09"

Those both result in tooltip and PDF software displays of date/time as 12-Mar-2025, 20:00:39.

Aside from the obvious appearance that the timezone offsets are possibly erroneous repetitions of the hour and minute values, do values like these (both the offsets and the displayed dates/times) have any logic in any context whatsoever?

That is crazy.  I'd say the software that wrote these dates is buggy.  But your tooltip/PDF software is displaying what I would expect if your time zone is -04:00 (resulting local time is the stored value minus the stored time zone plus your time zone).

Huh. My proper timezone offset right now is indeed -04:00, though I wouldn't have expected tooltips and software to utilize both the stored offset AND my actual timezone in determining what to display. Thanks for the info.
