-Subject: [PATCH] time: add support for time64 libc
-
-libcs are implementing changes to fix the year 2038 issue on 32 bit
-platforms (see [1]). musl libc already went ahead and implemented it,
-starting with musl-1.2.0 (see [2]).
-
-Running asterisk on a 32 bit box with a time64 libc causes some
-problems. For instance registering to pjsip doesn't work. The
-registration completes fine, but the AOR disappears immediately, making
-the registered clients unreachable.
-
-This commit adds two new definitions to include/asterisk/time.h:
-
-TIME_T_INT_FMT
-TIME_T_UINT_FMT
-
-If __USE_TIME_BITS64 is defined (by a time64 libc, see [1]), they're set
-to the proper conversions for type int64_t, PRId64 and PRIu64
-respectively. If __USE_TIME_BITS64 is not defined, the status quo
-remains unchanged ("%ld" and "%lu" are used).
-
-The new definitions are used in the different parts of asterisk, where
-appropriate.
-
-These changes get rid of the new warnings that appeared with musl-1.2.0 and
-make the pjsip registration work again. Below an example warning:
-
-In file included from ../include/asterisk.h:23,
-                 from res_pjsip/location.c:19:
-res_pjsip/location.c: In function 'expiration_struct2str':
-../include/asterisk/astmm.h:270:72: warning: format '%ld' expects argument of type 'long int', but argument 6 has type 'time_t' {aka 'long long int'} [-Wformat=]
-  270 |         __ast_asprintf(__FILE__, __LINE__, __PRETTY_FUNCTION__, (ret), (fmt), __VA_ARGS__)
-      |                                                                        ^~~~~
-res_pjsip/location.c:492:17: note: in expansion of macro 'ast_asprintf'
-  492 |         return (ast_asprintf(buf, "%ld", contact->expiration_time.tv_sec) < 0) ? -1 : 0;
