NAME

       __pmConvertTime - convert tm structure to timeval structure

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/impl.h>

       int __pmConvertTime(struct tm *tmin, struct timeval *origin, struct timeval *rslt);

       cc ... -lpcp

DESCRIPTION

       __pmConvertTime	accepts  a  tm	structure that has been filled in by __pmParseCtime(3) and a reference time point origin, and fills in the
       given rslt structure with the time the user meant when he specified a partial ctime or positive or negative time interval.

       Typically, the argument origin is the start time for a PCP archive log, unless the user specified a negative interval offset, in which case
       it is the end time of the log.

       __pmConvertTime returns 0 if successful.  It returns -1 and writes an error message to stderr, if an error is detected.

       Use pmNewZone(3), pmNewContextZone(3) or pmUseZone(3) to establish a new current timezone that will effect __pmConvertTime.

NAME

       __pmParseCtime - convert ctime(3) string to tm structure

C SYNOPSIS

       #include <pcp/pmapi.h>
       #include <pcp/impl.h>

       int __pmParseCtime(const char *string, struct tm *rslt, char **errmsg);

       cc ... -lpcp

DESCRIPTION

       __pmParseCtime reverses the asctime(3C) function.  It accepts a string specifying a time, and fills in the given tm structure.

       Either  a  fully specified asctime(3C) string like "Mon Mar  4 13:07:47 1996" or a partially specified time like '1996", "Mar 1996", "Mar 4
       1996", "Mar", "13:07:47", "13:07", "Mar 4 13:07:47",... is accepted.  In addition, the seconds component may be a  floating  point  number,
       for example "13:07:47.5".  The 12 hour clock is also supported, so "13:07" and "1:07 pm" are equivalent.

       __pmParseCtime returns 0 if successful.	It returns -1 and a dynamically allocated error message string in errmsg, if the given string does
       not parse.  Be sure to free(3C) the error message string.

       The tm structure returned in rslt should only be used as an argument to the __pmConvertTime function, as it  contains  encoded  information
       that will only be correctly interpreted by __pmConvertTime.
