NAME
utc_localtime - Converts a binary timestamp to a tm structure that
expresses local time
SYNOPSIS
#include <dce/utc.h>
int utc_localtime( struct tm *timetm,
long *tns,
struct tm *inacctm,
long *ins,
utc_t *utc );
PARAMETERS
Input
utc
Binary timestamp. Use NULL if you want this routine to use the
current time for this parameter.
Output
timetm
Time component of the binary timestamp, expressing local time.
tns
Nanoseconds since the Time component of the binary timestamp.
inacctm
Seconds of the inaccuracy component of the binary timestamp.
If the inaccuracy is finite, then tm_mday returns a value of -1
and tm_mon and tm_year return values of 0 (zero). The field
tm_yday contains the inaccuracy in days. If the inaccuracy is
unspecified, all tm structure fields return values of -1.
ins
Nanoseconds of the inaccuracy component of the binary timestamp.
If the inaccuracy is unspecified, ins returns a value of -1.
DESCRIPTION
The utc_localtime() routine converts a binary timestamp to a tm
structure that expresses local time.
The user's environment determines the time zone rule (details are
system dependent).
If the user's environment does not specify a time zone rule, the
system's rule is used (details of the rule are system dependent).
For example, on OpenVMS systems, the rule pointed to by the
filename in SYS$SYSTEM:SYS$TIMEZONE_SRC.DAT applies.
Additional returns include nanoseconds since Time and nanoseconds of
inaccuracy.
RETURN VALUES
0 Indicates that the routine executed successfully.
-1 Indicates an invalid time argument or invalid results.
EXAMPLES
See the sample program in the utc_gmtzone reference page.
