QString QDateTime::toString ( const QString & format ) const
Returns the datetime as a string. The format parameter determines the format of the result string.
These expressions may be used for the date:

Expression	Output
d	the day as number without a leading zero (1 to 31)
dd	the day as number with a leading zero (01 to 31)
ddd	the abbreviated localized day name (e.g. 'Mon' to 'Sun'). Uses QDate::shortDayName().
dddd	the long localized day name (e.g. 'Monday' to 'Qt::Sunday'). Uses QDate::longDayName().
M	the month as number without a leading zero (1-12)
MM	the month as number with a leading zero (01-12)
MMM	the abbreviated localized month name (e.g. 'Jan' to 'Dec'). Uses QDate::shortMonthName().
MMMM	the long localized month name (e.g. 'January' to 'December'). Uses QDate::longMonthName().
yy	the year as two digit number (00-99)
yyyy	the year as four digit number

These expressions may be used for the time:

Expression	Output
h	the hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display)
hh	the hour with a leading zero (00 to 23 or 01 to 12 if AM/PM display)
m	the minute without a leading zero (0 to 59)
mm	the minute with a leading zero (00 to 59)
s	the second without a leading zero (0 to 59)
ss	the second with a leading zero (00 to 59)
z	the milliseconds without leading zeroes (0 to 999)
zzz	the milliseconds with leading zeroes (000 to 999)
AP	use AM/PM display. AP will be replaced by either "AM" or "PM".
ap	use am/pm display. ap will be replaced by either "am" or "pm".

All other input characters will be ignored. Any sequence of characters that are enclosed in singlequotes will be treated as text and not be used as an expression. Two consecutive singlequotes ("''") are replaced by a singlequote in the output.
Example format strings (assumed that the QDateTime is 21 May 2001 14:13:09):

Format	Result
dd.MM.yyyy	21.05.2001
ddd MMMM d yy	Tue May 21 01
hh:mm:ss.zzz	14:13:09.042
h:m:s ap	2:13:9 pm

If the datetime is invalid, an empty string will be returned.

谢谢您的回复，

我在format时用MMM，结果是“一月”，并不是“Jan”，这个语言在哪里设置？

很遗憾，您需要改变系统语言为英语，因为qdatetime读取的是系统接口时间，所以。。
要是怕麻烦，显示数字月份又何妨呢？

向您具体介绍下我的问题：

我接收英文网站的信息，其中有日期、时间等信息，例如：Wed, 13 Jan 2010 15:36:23 GMT，我现在要把它改成13 Jan 15:36

我想用QDateTime::fromString("Wed, 13 Jan 2010 15:36:23 GMT", Format1);

QString afterFormat = QDateTime::toString(Format2);

Format1、Format2中的“MM”使结果都变成了中文，所以……

谢谢您的提醒，问题解决了。

QLocale local(QLocale::English, QLocale::AmericanSamoa);

QDateTime dt = local.toDateTime("Wed, 13 Jan 2010 15:36:23","ddd, dd MMM yyyy hh:mm:ss");
