In the Windows C Runtime the strings in the global array _tzname[]

They must be converted to UTF8 before use by Wireshark/GTK.

to a "time_fmt.h" file, included by the headers that use it. Have
abs_time_to_str() and abs_time_secs_to_str() take the date format value,
rather than a Boolean "show this as UTC" flag, as an argument. Document
the ABSOLUTE_TIME_ formats a bit better. Use that format in the CCSDS

epan/dissectors/packet-ncp2222.inc is a bit hard to fix, so we're not
ready to enable that warning by default yet.
Throw in some casts to handle GLib routines that take arbitrary
non-const pointers (they can later return the pointers, and some
callers might want to modify or free up those pointers in cases where
they're known to be writable or allocated).
Use ep_tvb_memdup() rather than a combination of ep_alloc() and
tvb_memcpy().
Clean up some indentation.

MSVC 2005 crashes, if localtime is called with very large numbers (in this case 218939827321) - probably due to changes that time_t is now 64bits long as default

IMO, the function should return an error string instead of cowardly
bailing out with an empty string.
inet_ntop does the latter by default, so it does not need any additional
check, just passing buf_len instead of INET6_ADDRSTRLEN.
At the other side I like the check you made into ip_to_str_buf.
My proposal would be to combine the patches and use MAX_IP_STR_LEN,
and approach below for both IPv4 and IPv6 in address_to_str_buf.
Have the error string return a more descriptive clue.

This functin was in a recent profiling run the fifth most expensive function.
It consumed ~3.5% of the total cpu in that run.
Using a static table this function is now just over twice as fast as previously.
My testrun calling it 10.000.000 times in a loop changed the execution time from ~17.3s ro ~8.2s
If this test was representative for the speedup and if ~3.5 in the profile run
was representative for normal cases this should make ethereal ~1.8% faster.
Woohoo.

Use that routine in the RADIUS dissector, rather than using "ctime()"

fractions-of-a-second (the units of which are either milliseconds or

Rename "rel_time_to_str()" to "rel_time_to_secs_str()", and add a

"rel_time_to_secs_str()" to format FT_RELATIVE_TIME values for now; we
