     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 :)
