| inDaylightTime |
(TimeZone timezone, Number unixtime) |
yoix.util |
| |
If the time indicated by
unixtime
falls within the limits of daylight savings time for
timezone,
then a non-zero value is returned.
Otherwise, zero is returned.
This function duplicates the
TimeZone
built-in
dst,
which is the preferred method of obtaining DST information.
Consequently, this function may be removed in a later release.

| Example: |
In the following example, two dates are tested for occurring during
a period of Eastern Daylight Savings Time.
import yoix.stdio.*;
import yoix.util.*;
double tm = 959832000;
TimeZone zone = getTimeZone("EST");
printf("%s is%s in daylight savings time\n",
date(zone, tm), inDaylightTime(zone, tm) ? "" : " not" );
tm += 15814800.;
printf("%s is%s in daylight savings time\n",
date(zone, tm), inDaylightTime(zone, tm) ? "" : " not" );
The results on standard output are:
Thu Jun 1 0:00:00 EDT 2000 is in daylight savings time
Fri Dec 1 0:00:00 EST 2000 is not in daylight savings time
