This arranges for the following 461 # functions to be added to the time conversion library. 462 # "offtime" is like "gmtime" except that it accepts a second (long) argument 463 # that gives an offset to add to the time_t when converting it. 464 # "offtime_r" is to "offtime" what "gmtime_r" is to "gmtime". 465 # I.e., "offtime" and "offtime_r" are like calling "localtime_rz" 466 # with a fixed-offset zone. 467 # "timelocal" is nearly equivalent to "mktime". 468 # "timeoff" is like "timegm" except that it accepts a second (long) argument 469 # that gives an offset to use when converting to a time_t. 470 # I.e., "timeoff" is like calling "mktime_z" with a fixed-offset zone. 471 # "posix2time" and "time2posix" are described in an included manual page. 472 # X3J11's work does not describe any of these functions. 473 # These functions may well disappear in future releases of the time 474 # conversion package. 475 # 476 # If you don't want functions that were inspired by NetBSD, add 477 # -DNETBSD_INSPIRED=0 478 # to the end of the "CFLAGS=" line. Otherwise, the functions 479 # "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the 480 # time library, and if STD_INSPIRED is also defined to nonzero the functions 481 # "posix2time_z" and "time2posix_z" are added as well. 482 # The functions ending in "_z" (or "_rz") are like their unsuffixed 483 # (or suffixed-by-"_r") counterparts, except with an extra first 484 # argument of opaque type timezone_t that specifies the timezone. 485 # "tzalloc" allocates a timezone_t value, and "tzfree" frees it. 486 # 487 # If you want to allocate state structures in localtime, add 488 # -DALL_STATE 489 # to the end of the "CFLAGS=" line.
