| ## utc_anytime(3dts) Converts a binary timestamp to a tm structure Synopsis #include <dce/utc.h> int utc_anytime( struct tm *timetm, long *tns, struct tm *inacctm, long *ins, long *tdf, 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 expressed in the timestamp's 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. tdf TDF component of the binary timestamp in units of seconds east of GMT. Description The utc_anytime( ) routine converts a binary timestamp to a tm structure by using the TDF information contained in the timestamp to determine the TDF returned with the tm structure. The TDF information contained in the timestamp is returned with the time and inaccuracy components; the TDF component determines the offset from GMT and the local time value of the tm structure. 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 The following example converts a timestamp by using the TDF information in the timestamp, and then prints the result. utc_t evnt; struct tm tmevnt; timespec_t tevnt, ievnt; char tznam[80]; /* Assume evnt contains the timestamp to convert... * * Get time as a tm structure, using the time zone information in * the timestamp... */ utc_anytime(&tmevnt, /* Out: tm struct of time of evnt */ (long *)0, /* Out: nanosec of time of evnt */ (struct tm *)0, /* Out: tm struct of inacc of evnt */ (long *)0, /* Out: nanosec of inacc of evnt */ (int *)0, /* Out: tdf of evnt */ &evnt); /* In: binary timestamp of evnt */ /* Get the time and inaccuracy as timespec structures... */ utc_bintime(&tevnt, /* Out: timespec of time of evnt */ &ievnt, /* Out: timespec of inacc of evnt */ (int *)0, /* Out: tdf of evnt */ &evnt); /* In: Binary timestamp of evnt */ /* Construct the time zone name from time zone information in the * timestamp... */ utc_anyzone(tznam, /* Out: Time zone name */ 80, /* In: Size of time zone name */ (long *)0, /* Out: tdf of event */ (long *)0, /* Out: Daylight saving flag */ &evnt); /* In: Binary timestamp of evnt */ /* Print timestamp in the format: * * 1991-03-05-21:27:50.023I0.140 (GMT-5:00) * 1992-04-02-12:37:24.003Iinf (GMT+7:00) */ printf("%d-%02d-%02d-%02d:%02d:%02d.%03d", tmevnt.tm_year+1900, tmevnt.tm_mon+1, tmevnt.tm_mday, tmevnt.tm_hour, tmevnt.tm_min, tmevnt.tm_sec, (tevnt.tv_nsec/1000000)); if ((long)ievnt.tv_sec == -1) printf("Iinf"); else printf("I%d.%03d", ievnt.tv_sec, (ievnt.tv_nsec/1000000)); printf(" (%s)\n", tznam); Related Information Functions: utc_mkanytime(3dts) utc_anyzone(3dts) utc_gettime(3dts) utc_getusertime(3dts) utc_gmtime(3dts) utc_localtime(3dts) ##
