Note: this code assumes that our time_t estimation is not too far away
from real value (we assume that localtime_r(tmp) will return something
within 24 hrs from t) which is probably true for all current time zones.
Note2: For the dates, which have time_t representation close to
MAX_INT32 (efficient time_t limit for supported platforms), we should
do a small trick to avoid overflow. That is, convert the date, which is
two days earlier, and then add these days to the final value.
The same trick is done for the values close to 0 in time_t
representation for platfroms with unsigned time_t (QNX).
To be more verbose, here is a sample (extracted from the code below):
(calc_daynr(2038, 1, 19) - (long) days_at_timestart)*86400L + 4*3600L
would return -2147480896 because of the long type overflow. In result
we would get 1901 year in localtime_r(), which is an obvious error.
Alike problem raises with the dates close to Epoch. E.g.
(calc_daynr(1969, 12, 31) - (long) days_at_timestart)*86400L + 23*3600L
will give -3600.
On some platforms, (E.g. on QNX) time_t is unsigned and localtime(-3600)
wil give us a date around 2106 year. Which is no good.
Theoreticaly, there could be problems with the latter conversion:
there are at least two timezones, which had time switches near 1 Jan
of 1970 (because of political reasons). These are America/Hermosillo and
America/Mazatlan time zones. They changed their offset on
1970-01-01 08:00:00 UTC from UTC-8 to UTC-7. For these zones
the code below will give incorrect results for dates close to
1970-01-01, in the case OS takes into account these historical switches.
Luckily, it seems that we support only one platform with unsigned
time_t. It's QNX. And QNX does not support historical timezone data at all.
E.g. there are no /usr/share/zoneinfo/ files or any other mean to supply
historical information for localtime_r() etc. That is, the problem is not
relevant to QNX.
We are safe with shifts close to MAX_INT32, as there are no known
time switches on Jan 2038 yet :)
