isoparse function from python-dateutil The python-dateutil package has dateutil.parser.isoparse to parse not only RFC 3339 datetime strings like the one in the question, but also other ISO 8601 date and time strings that don’t comply with RFC 3339 (such as ones with no UTC offset, or ones that represent only a date). >>> import dateutil.parser … Read more
This solves the problem: DateTimeFormatter formatter = new DateTimeFormatterBuilder() .appendPattern(“yyyy-MM-dd HH:mm:ss”) .appendFraction(ChronoField.MICRO_OF_SECOND, 0, 6, true) .toFormatter(); System.out.println(LocalDateTime.parse(“2015-05-07 13:20:22.276052”, formatter)); System.out.println(LocalDateTime.parse(“2015-05-07 13:20:22.276”, formatter)); System.out.println(LocalDateTime.parse(“2015-05-07 13:20:22”, formatter)); // output 2015-05-07T13:20:22.276052 2015-05-07T13:20:22.276 2015-05-07T13:20:22 The answer by JiriS is incorrect, as it uses appendValue whereas the correct way is to use DateTimeFormatterBuilder.appendFraction (which also handles the decimal point).

Twitter dates in specific are interesting because they are relative only for the first day. After 24 hours they just show the month and day. After a year they start showing the last two digits of the year. Here’s a sample function that does something more akin to Twitter relative dates, though it always shows … Read more
If you want to parse all valid formats of offsets (Z, ±hh:mm, ±hhmm and ±hh), one alternative is to use a java.time.format.DateTimeFormatterBuilder with optional patterns (unfortunatelly, it seems that there’s no single pattern letter to match them all): DateTimeFormatter formatter = new DateTimeFormatterBuilder() // date/time .append(DateTimeFormatter.ISO_LOCAL_DATE_TIME) // offset (hh:mm – “+00:00” when it’s zero) .optionalStart().appendOffset(“+HH:MM”, … Read more
std::tm tm = {}; std::stringstream ss(“Jan 9 2014 12:35:34”); ss >> std::get_time(&tm, “%b %d %Y %H:%M:%S”); auto tp = std::chrono::system_clock::from_time_t(std::mktime(&tm)); GCC prior to version 5 doesn’t implement std::get_time. You should also be able to write: std::tm tm = {}; strptime(“Thu Jan 9 2014 12:35:34”, “%a %b %d %Y %H:%M:%S”, &tm); auto tp = std::chrono::system_clock::from_time_t(std::mktime(&tm));
datetime.datetime.strptime has problems with timezone parsing. Have a look at the dateutil package: >>> from dateutil import parser >>> parser.parse(“Tue May 08 15:14:45 +0800 2012”) datetime.datetime(2012, 5, 8, 15, 14, 45, tzinfo=tzoffset(None, 28800))
See: Mozilla Core JavaScript Reference: Date object Mozilla Core JavaScript Reference: String.Split Code: var strDate = “03.09.1979”; var dateParts = strDate.split(“.”); var date = new Date(dateParts[2], (dateParts[1] – 1), dateParts[0]);
You can use dateutil.parser.parse (install with python -m pip install python-dateutil) to parse strings into datetime objects. dateutil.parser.parse will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime which you supply a format string to (see Brent Washburne’s answer). from dateutil.parser import parse … Read more
This solution makes use of the DateTimeStyles enumeration, and it also works with Z. DateTime d2 = DateTime.Parse(“2010-08-20T15:00:00Z”, null, System.Globalization.DateTimeStyles.RoundtripKind); This prints the solution perfectly.
Python 2.6 added a new strftime/strptime macro %f. The docs are a bit misleading as they only mention microseconds, but %f actually parses any decimal fraction of seconds with up to 6 digits, meaning it also works for milliseconds or even centiseconds or deciseconds. time.strptime(’30/03/09 16:31:32.123′, ‘%d/%m/%y %H:%M:%S.%f’) However, time.struct_time doesn’t actually store milliseconds/microseconds. You’re … Read more
