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. If you are happy with lubridate's year function, you could just use its (very simple) code: as.POSIXlt(x, tz = tz(x))$year + 1900 In general, you should avoid conversions between any types/classes and characters when...
How to use varchar minus sign for mathematical operation in SQL Server 2008?
First, you do not need nested select for what you are doing. 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...

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...

Need a timestamp with microseconds as Decimal
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...
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 <<...

Issue on converting time from local to UTC at DST end date while using TimeZoneInfo.ConvertTimeToUtc(DateTime, TimeZoneInfo) method
Isn't this wrong? why did the converted time increase by an hour on 1st November? Because that's when the clocks change, as you say. The problem is that "2015-11-01 01:49:00.000" is ambiguous in Pacific Time - it occurs twice, once at 2015-11-01T08:49:00Z and once at 2015-11-01T09:49:00Z. A DateTime can...

Can I plot times when they're given as UNIX timestamps with added milliseconds?
The precision must be given only for the output. For parsing, the seconds (or the timestamp) are treated as floating numbers. But reading in a time stamp with milliseconds seems to be supported only since version 4.6.4 (tested here). But, there is a workaround: specifying ($1) instead of 1 in...

It allows any text to be associated with a value when formatting or parsing, which solves the problem effectively and elegantly: Map<Long, String> monthNameMap = new HashMap<>(); map.put(1L, "Jan."); map.put(2L, "Feb."); map.put(3L, "Mar."); DateTimeFormatter fmt =...

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...

Is CurrentUICulture.DateTimeFormat different on OS and .NET version?
You are correct that the default short-date format for en-CA was changed, as of .NET 4.0. You can test this yourself: Console.WriteLine(new CultureInfo("en-CA").DateTimeFormat.ShortDatePattern); Running on .NET 2 runtime (framework 2.0/3.x) will give "dd/MM/yyyy". Running on .NET 4 runtime (framework 4.x) will give "yyyy-MM-dd". This is described in the MSDN document:...
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. This is silly - you already have the DateTime from the ParseExact method: string str = "27-07-2015 6:15 pm"; var dt = DateTime.ParseExact(str, "dd-MM-yyyy h:mm tt", null); That's it,...
