Details:
This fails with gnustep but works on Mac OS X:
NSDateFormatter *df;
NSTimeInterval t = 650498989.396999955177;
NSDate *d;
NSString *s;
df = [NSDateFormatter new];
[df setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];
[df setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
[df setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
d = [[[NSDate alloc] initWithTimeIntervalSinceReferenceDate:t]
autorelease];
s = [df stringFromDate:d];
NSAssert([@"2021-08-12T22:09:49.397Z" isEqualToString:s], @"botch: should
get 2021-08-12T22:09:49.397Z but got %@", s);
with
2021-08-12 22:40:28.689 gnustep-base-tests[57679:57679]
gnustep-base-tests.m:610 Assertion failed in GnustepBaseTests(instance),
method nsdate. botch: should get 2021-08-12T22:09:49.397Z but got
2021-08-12T22:09:49.396Z
because gnustep-base's NSDateFormatter apparently truncates fractional seconds
rather than rounding. (This is as of gnustep-base 1.27.0).
