问题 I'm having a problem with the NSDateFormatter . It is returning null for some specific dates. I did this function to debug the case: - (void) debugTest:(NSString *)dateStr{ NSLog(@"String: %@", dateStr); NSDateFormatter *df = [[NSDateFormatter alloc] init]; [df setDateFormat:@"yyyy-MM-dd"]; NSDate *dateObj = [df dateFromString: dateStr]; NSLog(@"Date: %@", dateObj); } This is my log output for some dates: String: 2012-10-18 Date: 2012-10-18 03:00:00 +0000 String: 2012-10-19 Date: 2012-10-19

问题 I have done following code: String str = "2013-01-17 11:26"; DateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd hh:MM"); Date date = dateFormat.parse(str); System.out.println("str :"+str); System.out.println("Date :"+date); Output str :21-01-2013 11:26 Date :Sat Feb 21 11:01:00 IST 2015 But something is wrong.

问题 I want to parse date strings like "February 7, 2011" using "M dd, yyyy" format. But I get an exception. 回答1: Your parsing string is not correct as mentioned by others To correctly parse February you need to use an english Locale or it may fail if your default Locale is not in English DateFormat df = new SimpleDateFormat("MMM dd, yyyy", Locale.ENGLISH); Date dt = df.parse("February 7, 2011"); 回答2: Try this code. I ran it with two dates "November 20, 2012" and "January 4, 1957" and got this

问题 It appears I can't use the javascript Date object as it inherintly defaults to US dates when you initialise with a datestring. There is no way of passing any culture information to the date object I.e. No matter what the clients locale settings are var d = new Date("08/10/2009") will always create a date object representing the 10th August 2009 rather than the 8th October 2009 if the clients locale was the UK. So given that my requirement is to be able to add/subtract days/months/years easily

问题 I have a table with a large number of rows. One column contains dates in the format '%m/%d/%Y' and I want to change all of them to format '%Y-%m-%d' the usual: update table set mydate = '6' doesn't work I guess because the date is always changing. How would I do that in this case? 回答1: If the fields in the date string are properly padded with zeros, you can extract them as substrings: UPDATE MyTable SET MyDate = substr(MyDate, 7, 4) || '-' || substr(MyDate, 1, 2) || '-' || substr(MyDate, 4, 2

When you convert util's Date to string it comes in this format('dow mon dd hh:mm:ss zzz yyyy'). But when I execute code, It gives me Exception. I Don't know what
