NAME

       date_from_tm - convert between tm struct and Windows DATE value

SYNOPSIS

       #include <synce.h>

       bool date_from_tm(struct tm *pTm, DATE *pDateOut);

       bool date_to_tm(DATE dateIn, DWORD dwFlags, struct tm *pTm);

DESCRIPTION

       The  date_from_tm() function converts a tm struct into the Windows DATE
       field pointed to by pDateOut.  Only years after 1900 are converted. The
       fields tm.tm_wday, tm.tm_yday and tm.tm_isdst are not used.

       date_to_tm() does the reverse. It only fills the fields tm_sec, tm_min,
       tm_hour, tm_year, tm_day, tm_mon. Dates before January 1st 1900 are not
       supported.   dwFlags  should  be 0, DATE_TIMEVALUEONLY to omit the date
       information or DATE_DATEVALUEONLY to omit time information. Whereas the
       tm.tm_year  field  usually  holds  the number of years since 1900, this
       function provides the complete year.

RETURN VALUE

       Both functions return FALSE on encountering an invalid  value  or  year
       earlier than 1900, or TRUE if successful.
