The SeismicXML sample code uses NSXMLParser to extract data from a
file downloaded from the USGS. The time of an event appears in the
file like this,
.....12:34:32Z....
According to rfc 822 'Z' means UTC (or GMT if you prefer).
I find that the NSDate from the parser is tagged as being in the
Pacific time zone, my local time zone, while the hours are correct for
UTC. That makes it 8 hours off for standard time.
The parser is told that the date format is,
[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
which seems to ignore the Z and impose local time.
I have tried several variations on that formatting string. They all
fail to deliver UTC.
[dateFormatter setDateFormat:@"yyyy-MM-dd' 'HH:mm:ssz"]; //says PDT
[dateFormatter setDateFormat:@"yyyy-MM-dd' 'HH:mm:ssZ"]; //says -0700
[dateFormatter setDateFormat:@"yyyy-MM-dd' 'HH:mm:sszz"]; //says PDT
[dateFormatter setDateFormat:@"yyyy-MM-dd' 'HH:mm:ss"]; //says
nothing but still thinks its PDT
No doubt my inexperience with the parser or NSDate is at fault. How do
I get the parser to recognize that the time really is UTC?
