Hi,
I have modelled calendar entries, which have a timestamp attribute. I
wanted to build a qualifier that matches all entries within a month
so I created start and end timestamps programatically. The start
timestamp is no problem. To get the end timestamp, I used
NSTimestamp.timestampByAddingGregorianUnits and added "a month minus
one second". This works fine for GMT, but gives me funky results for
e.g. Europe/Berlin. Please see code and output below. Any ideas? This
is with WO 5.3.3.
Timo
public class NSTimestampTest {
public static void main(String[] args) {
int year = 2008;
// This one works
NSTimeZone gmt = NSTimeZone.getGMT();
test(gmt, year);
// This one doesn't
NSTimeZone berlin = NSTimeZone.timeZoneWithName("Europe/Berlin",
false);
test(berlin, year);
}
private static void test(NSTimeZone timezone, int year) {
NSTimestampFormatter formatter = new NSTimestampFormatter("%Y-%m-%d
%H:%M:%S %Z");
formatter.setDefaultFormatTimeZone(timezone);
for (int month = 1; month <= 12; month++) {
NSTimestamp start = new NSTimestamp(year, month, 1, 0, 0, 0,
timezone);
NSTimestamp end = start.timestampByAddingGregorianUnits(0, 1, 0,
0, 0, -1);
System.out.printf("%s -> %s\n", formatter.format(start),
formatter.format(end));
}
}
}
results in
2008-01-01 00:00:00 Etc/GMT -> 2008-01-31 23:59:59 Etc/GMT
