NAME

librock_ssgmtime - Parse a date/time string, storing to struct tm or time_t

#License - #Source code - #Example Use -

SYNOPSIS

#include <time.h>
#include <librock/datime.h>

int
librock_ssgmtime(
    const char librock_PTR *sptr,
    librock_STRUCT_TM *tmptr,
    librock_TIME_T *time);

DESCRIPTION

Scans strings of the following formats, with the part from HH:MM:SS optional

    MM/DD/YYYY HH:MM:SS
    MM/DD/YY HH:MM:SS
    DD MonthNAME YYYY HH:MM:SS -/+NNNN  (NNNN are digits specifing the offset from GMT)
    DD MonthNAME YYYY HH:MM:SS GMT

Two digit years less than 60 will be windowed into the range 2000-2059,
otherwise in the range 1960-1999.

Note that this does not parse the day of week.

Returns the number of characters processed.
Typical use is

#ifdef librock_TYPICAL_USE_ssgmtime
    #include <time.h>
    #include <librock/datime.h>

    time_t t;
    char *ptr = "02/20/02 01:03:44";
    ptr += librock_ssgmtime(ptr,NULL,(librock_TIME_T *)&t);
    printf("%ld\n",(long) t);

    ptr = "20 Feb 2002 02:03:44 +0100";
    ptr += librock_ssgmtime(ptr,NULL,(librock_TIME_T *)&t);
    printf("%ld\n",(long) t);

#endif
