could very well cause a negate number get passed in and thus cause reading
outside of the array usually used for this purpose.
We avoid this by using the uppercase macro versions introduced just now that
does some extra crazy typecasts to avoid byte codes > 127 to cause negative
int values.
zone name of a daylight savings time was used. For example, PDT vs PDS. This
flaw was introduced with the new date parser (11 sep 2004 - 7.12.2).
Fortunately, no web server or cookie string etc should be using such time
zone names thus limiting the effect of this bug.
seems the Windows (MSVC) libc time functions may return data one hour off if
TZ is not set and automatic DST adjustment is enabled. This made
curl_getdate() return wrong value, and it also concerned internal cookie
expirations etc.
that feature 64 bit 'long'.
Some systems have 64 bit time_t and deal with years beyond 2038. However, even
some of the systems with 64 bit time_t returns -1 for dates beyond 03:14:07
UTC, January 19, 2038. (Such as AIX 5100-06)
