I think so. It certainly does not apply the DST rules applicable to the
date of the file. I used to understand this ... now I'm just confused.

Here's the reason I'm replying. I was asked to analyse the System event log
file from a computer that had crashed. The file could not be opened - Event
Viewer said "corrupted".

Anyway, after several hours of fiddling about, I found the simple cause
(and, no, it wasn't the fix that pops up in Google).

During this time I found that an event log file records each timestamp in
local time (as the number of seconds since start 1970). Furthermore, my
Event Viewer (after I had fixed the file) showed timestamps like 10:20am,
but the actual time in the file was 11:20am (one hour later). Some DST
madness, I assume.
