datetime-parsing

As an input I have a string which is a String in ISO 8601 to represent date. For example: "2017-04-04T09:00:00-08:00" The last part of String , which is "-08:00" denotes TimeZone Offset. I convert this string into a Calendar instance as shown below: Calendar calendar = GregorianCalendar.getInstance(); Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US).parse(iso8601Date); calendar.setTime(date); iso8601Date is "2017-04-04T09:00:00-08:00" But this does not pick timezone and if I get timezone from Calendar instance, it gives currently set instance of the laptop and does not

I have url that returns date in this format url_date = "2015-01-12T08:43:02Z" I don't know why there are strings, it would have been simpler to get it as "2015-01-1208:43:02" which would have been simpler to parse using datetime.datetime.strptime(url_date , '%Y-%m-%d') but it does not work. I have tried with %Y-%m-%d %Y-%m-%d-%H-%M-%S %Y-%m-%d-%H-%M-%S-%Z But I keep getting errors like "time data 2015-01-12T08:43:02Z does not match ..." The format you are looking for is - '%Y-%m-%dT%H:%M:%SZ' . Example - >>> url_date = "2015-01-12T08:43:02Z" >>> import datetime >>> datetime.datetime.strptime

I have time stamp in format 2017-18-08 11:45:30.345 . I want to convert it to epoch time, so I am doing below: String timeDateStr = "2017-18-08 11:45:30.345"; DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-dd-MM HH:mm:ss.SSS"); ZonedDateTime zdt = ZonedDateTime.parse(timeDateStr, dtf); System.out.println(zdt.toInstant().toEpochMilli()); I am getting below error: java.time.format.DateTimeParseException: Text '2017-18-08 11:45:30.345' could not be parsed: Unable to obtain ZonedDateTime from TemporalAccessor I also tried different formats but still getting errors. Note : originally the

I'm parsing a number of news feeds and each item's pubDate follows the same format: Sun, 11 Jun 2017 18:18:23 +0000 Unfortunately one feed does not: Sat, 10 Jun 2017 12:49:45 EST I have tried to parse the date with no luck using androids java date and SimpleDateFormat : try { Calendar cal = Calendar.getInstance(); TimeZone tz = cal.getTimeZone(); SimpleDateFormat readDate = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z"); readDate.setTimeZone(TimeZone.getTimeZone("UTC")); Date date = readDate.parse(rssDateTime); SimpleDateFormat writeDate = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss Z")

I am trying to create a DateTimeformatter to validate following date times: String date1 = "2017-07-06T17:25:28"; String date2 = "2017-07-06T17:25:28.1"; String date3 = "2017-07-06T17:25:28.12"; String date4 = "2017-07-06T17:25:28.123"; String date5 = "2017-07-06T17:25:28.1234"; String date6 = "2017-07-06T17:25:28.12345"; String date7 = "2017-07-06T17:25:28.123456"; String date8 = "2017-07-06T17:25:28."; I have tried the following date time formatter to validate above dates: public static final String DATE_TIME_FORMAT_PATTERN = "yyyy-MM-dd'T'HH:mm:ss"; DateTimeFormatter formatter1 = new

When I try to run the following code: LocalTime test = LocalTime.parse("8:00am", DateTimeFormatter.ofPattern("hh:mma")); I get this: Exception in thread "main" java.time.format.DateTimeParseException: Text '8:00am' could not be parsed at index 0 Any idea why this might be happening? The AM/PM tokens have* to be uppercase: LocalTime test = LocalTime.parse("8:00AM", DateTimeFormatter.ofPattern("hh:mma")); Patterns definitions for hours: Symbol Meaning Presentation Examples ------ ------------ ------------ -------- a am-pm-of-day text PM h clock-hour-of-am-pm (1-12) number 12 K hour-of-am-pm (0
