Python timezone offset wrong? [duplicate]
Instead of assigning the tzinfo parameter, use the localize method from pytz. tz = get_localzone() date = tz.localize(datetime(2015, 6, 17, 14, 58, 45)) This is discussed prominently in the pytz documentation, starting with the the first "Note" box, and in the very first code sample. It's also shown in the...

Don't understand tm_struct (C++) calculations - is there an offset of some kind? [closed]
From the documentation on tm we can see that: tm_year is years since 1900, not the current year number, i.e. it should be 115 this year. tm_mon is months since January (range 0-11), not the number of the month. So what you need is: std::cout << 1900 + nowTm->tm_year <<...

How to parse non-standard month names with DateTimeFormatter
java,datetime,localization,java-8,java-time
The answer to the problem is the DateTimeFormatterBuilder class and the appendText(TemporalField, Map) method.

How to use varchar minus sign for mathematical operation in SQL Server 2008?

So: SELECT (SELECT DATEADD(mi, left(@off,1)+(convert(int, SUBSTRING(@off,2,2)*60) + convert(int,RIGHT(@off,2))), @d)) as 'UTC-calc', is the same as: SELECT DATEADD(mi, left(@off,1)+(convert(int, SUBSTRING(@off,2,2)*60) + convert(int,RIGHT(@off,2))), @d)) as [UTC-calc], The problem is that the string + or - converts to 0 in an...

Android/Joda time - Convert dateTime to my local DateTime
android,datetime,timezone,jodatime
The solution i have found: in your application class, or somewhere else, initialise JodaTimeAndroid: JodaTimeAndroid.init(this); after this initialisation the date will be automatically converted to your zone, with proper offset.

Why is R (in my example) very slow for handling dates/datetimes?
A format function that can return many different formats, can be expected to be quite slow.

How get this date format CCYY-MM-DDThh:mm:ss.sss-hh:mm
A DateTime value has no format. The format is only significant when you represent the value as a string. In other words, the requirements that it be formatted as "CCYY-MM-DDThh:mm:ss.sss-hh:mm" and that it not be a string are mutually exclusive. If it really needs to be a DateTime, you should...

ParseExact inverse my day and month
As @Rawling correctly noted, you're parsing the datetime twice: first, using your custom formatting, and second, using the system's default formatting.

You could pass a float to the Decimal constructor directly: d = Decimal(stamp) CPython float uses C double that has more than enough precision to represent microseconds in the usual timestamp range. time.time() and datetime.utcnow() may produce slightly different results. The latter is rounded to microseconds: from datetime import datetime...
Format DateTime.ParseInfo
With ParseExact(): using System.Globalization; var value = "Mon Jun 15 2015 00:00:00 GMT+0200 (Central Europe Daylight Time)"; var trimedValue = value.Substring(0, value.IndexOf(" (")); var dateTime = DateTime.ParseExact(trimedValue, "ddd MMM dd yyyy HH:mm:ss 'GMT'zzz", CultureInfo.InvariantCulture); ...
Converting DateTime throws SqlDateTime overflow
You should not use Convert.ToDateTime like that. You should use DateTime.Parse or DateTime.ParseExact. DateTime temp = DateTime.ParseExact(time, "yyyy-MM-dd hh:mm:ss tt", CultureInfo.InvariantCulture); Since DateTime.Parse(temp) worked for you, you can leave it as that. Edit: The difference between the two methods is very important in this situation. Convert.ToDateTime(s) This method will call...
UTC Time different on servers in different timezones?
c#,sql-server,asp.net-mvc,datetime,timezone
Is it possible that the incorrect result is actually on your machine and not Azure, and is because you are initialising ScheduledDateUtc as local time and not UTC? Consider these two lines of code: new DateTime(2015, 6, 1, 1, 1, 1).AddHours(5).ToUniversalTime().Dump(); new DateTime(2015, 6, 1, 1, 1, 1, DateTimeKind.Utc).AddHours(5).ToUniversalTime().Dump(); Here,...
converting “1984-03-25 02:00:00” to POSIX gives NA
While you don't say what your timezone is, this looks like Daylight Saving Time (DST) issue. In timezones that use DST, there will be a day where the hour "jumps" from 1:59:59.999 to 3:00:00.000. This means that any times in the 2AM hour do not exist on this day. My...
Oracle NVL function not allows second parameter as datetime
From here: The first parameter to NVL is determining the expected datatype of the returned column, with the trunc function defaulting that to NUMBER because it's parameter is NULL. The second parameter to NVL needs to match that datatype which it doesn't because it is a date. SQL> select nvl(trunc(sysdate),...
SQL Server 2008 two tables with common dates field how to select by datewise from both tables

PostgreSQL - aggregating data by date from datetime field

Format datetime to YYYY-MM-DD HH:mm:ss in moment.js

Parsing two different formats of dates in data frame
python,parsing,datetime,pandas,dataframes
Instead of using to_datetime(), first parse your strings with dateutil.parser.parse(): In [2]: from dateutil.parser import parse In [3]: dt1 = "Tue Nov 4 12:01:15 2014" In [4]: dt2 = "2014-11-04 13:15:13 +0000" In [5]: parse(dt1) Out[5]: datetime.datetime(2014, 11, 4, 12, 1, 15) In [6]: parse(dt2) Out[6]: datetime.datetime(2014, 11, 4, 13,...
How to compare sql datetime and c# datetime
You can use the SqlDateTime structure. DateTime now = DateTime.Now; SqlDateTime sqlNow = new SqlDateTime(now); bool equal = now == sqlNow.Value; // false So if you have a DateTime and want to know if it's equal to a DB-DateTime use: Assert.Equal(dbEndTime, new SqlDateTime(endTime).Value); // true SqlDateTime: Represents the date and...
