问题 I'm trying to plot 'time of day' per week during 2000-2011. This is a follow-up to my earlier question Aggregating mean “%H%M” in “week” I would like to be able to use scale_x_date of ggplot2, but I'm having a hard time to transform my Group.1 chr which is %W/%g back to a Date format to be able to use this particular scale. I have tried a few different things, including the script below, but I don't end-up with what I am expecting...? out$Group.1<-as.Date(out$Group.1, "%W/%g") out$Group.1 [1]

问题 I'm trying to save a date in database with ASP.NET. The datatype of Date in the database is datetime . I want to save it as for example (23/02/2014 00:00:00) That is, I want to save Date, Month and Year, and then have time always be 00:00:00. I also want to have zeros before month and/or day when they are only one number. e.g. 02/06/2014 instead of 2/6/2014. This is possible when the datatype is varchar but how would I do this when the datatype is datetime ? 回答1: dateTime.ToString("dd/MM/yyyy

问题 I've build this dashboard with multiple date and time columns however in the dashboard the "T" and "Z" popup in the display Any ideas on how to remove this? I tried as.character , as.factor , anytime but I'm not able to make it happen. Any other ideas are appreciated! 回答1: You can parse it in base R or with lubridate : tz <- Sys.timezone() date1 <- "2015-03-23T13:23:20Z" # With {base} strptime(date1, tz = tz, format = "%Y-%m-%dT%H:%M:%OSZ") [1] "2015-03-23 13:23:20 CET" #With lubridate

问题 I am using the following code to get the date in ISO-8601 format. For UTC the value returned does not contain offset. OffsetDateTime dateTime = OffsetDateTime.ofInstant( Instant.ofEpochMilli(epochInMilliSec), zoneId); return dateTime.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME); For other time formats the response returned looks like: 2016-10-30T17:00:00-07:00 In case of UTC the value returned is: 2016-10-30T17:00:00Z I want it to be: 2016-10-30T17:00:00+00:00 Note: Do not use UTC-0 as -00

问题 I'm using Google's API Explorer for their Calendar API on this page. I am inserting an event { "end": { "dateTime": "2016-10-31T06:30:00Z" }, "start": { "dateTime": "2016-10-31T06:00:00Z" } } and have tried the following datetime formats: 2016-10-31T06:00:00Z 2016-10-31T06:00:00-00:00 2016-10-31T06:00:00+00:00 But no matter input format, Google chooses to add an hour when setting the datetime. The response is always: "start": { "dateTime": "2016-10-31T07:00:00+01:00" } I'm currently in

问题 In the java.time classes, how do we specify a formatting pattern for a DateTimeFormatter that allows for either a FULL STOP ( . ) (period or dot) or a COMMA ( , ) as the delimiter of a fractional second? For example, the following works for parsing an input date value ending in either .0Z or ,0Z in 20090813145607.0Z and 20090813145607,0Z . String input = "20090813145607.0Z"; DateTimeFormatter f = DateTimeFormatter.ofPattern ( "uuuuMMddHHmmss[,S][.S]X" ); But for printing, the output contains

问题 I have a date: var date = new DateTime(2017,6,14,13,0,0); and a textview to display it.

Thank you! 回答1: On Xamarin.Android it is a bit different than on Android as described in Muhammads answer: var date = new DateTime(2017, 6, 14, 13, 0, 0); var is24hour = Android.Text.Format.DateFormat.Is24HourFormat
