I'm trying to add 2 DateTime fields which are stored as strings in Azure. The first datetime is supposed to get the current date and time now and this stores the date time as 12/02/2019 09:01 correctly, but currently the second field is supposed to get the current date and time and add 30 minutes but it is storing is like only the date eg 12/02/2019. This is my current code:
symptomFeedback.DateTime = DateTime.Now.ToString("dd/MM/yyyy HH:mm");
symptomFeedback.Datetimelimit = DateTime.Now.AddMinutes(30).ToString("dd/MM/yyyy HH:mm");

I am making api's in laravel and getting 2021-01-30T10:30:17.704 05:30 from $request->followup and i have column in database named followup having datetime datatype. But it's giving me following error.
Carbon\Exceptions\InvalidFormatException: Could not parse '2021-01-30T10:30:17.704 05:30': DateTime::__construct(): Failed to parse time string (2021-01-30T10:30:17.704 05:30) at position 24 (0): Double time specification in file D:\xampp2\htdocs\synocrm-baid\rest-apis\vendor\nesbot\carbon\src\Carbon\Traits\Creator.php on line 188
I tried to change format like
$followupDate = date('Y-m-d h:i:s A',strtotime($request->followup));
My modal having
#property Carbon|null $followup
$request->followup is appending datetime with datetime
Original Value: 2021-01-30T10:30:17.704 05:30
Datetime: 2021-01-30T10:30:17.704
Time: 05:30
As we can see, there is two Time (05:30 and 10:30:17), because of which the strtotime() cannot convert the value.
In order to fix the problem,
Send the value as time time only (2021-01-30T10:30:17.704) instead of two times Time attribute
If you have no control over request value, you can retrieve only date value like:
$dateValue = explode(' ', $request->followup)[0];
$followupDate = date('Y-m-d h:i:s A',strtotime($dateValue));
Or Using Carbon
$followupDate = Carbon::parse($dateValue);
I would not recommend option 2 because it creates problems and confusion for other devs.
2021-01-30T10:30:17.704 05:30
It does not seem to valid timestamp. For parsing, it should be the valid timestamp or date.
I've converted a date into string. Now, I want to parse a string to get the DD part from DD-MM-YYYY.
For e.g.
If the date is 03-05-2017 (DD-MM-YYYY) then the goal is to get only first part of the string i.e. 03 (DD).
You've tagged this question as a ServiceNow question, so I assume you're using the ServiceNow GlideDateTime Class to derive the date as a string. If that is correct, did you know that you can actually derive the day of the month directly from the GlideDateTime object? You can use the getDayOfMonth(), getDayOfMonthLocalTime(), or getDayOfMonthUTC().
You could of course, also use String.prototype.indxOf() to get the first hyphen's location, and then return everything up to that location using String.prototype.slice().
Or, if you're certain that the day of the month in the string will contain an initial zero, you can simply .slice() out a new string from index 0 through index 2.
var date = '03-05-2017';
var newDate = date.slice(0, 2);
console.log(newDate); //==>Prints "03".
var alternateNewDate = date.slice(0, date.indexOf('-'));
console.log(alternateNewDate); //==>Prints "03".
I have column which stores only time. I want to convert to it into datetime and then to a specific timezone. When I do it on console using only the attribute, it shows correct conversion value. But when I use it in query the query shows the current time in UTC. Suppose I have time "05:15" stored in Central time. Now when I want to fetch records for a interval of 30 minutes plus and minus of this time, I do following,
day = Time.now
# departure_time_from _db below is the name of column in table which store time
departure = departure_time_from _db.change(:day => date.day, :month => date.month, :year => date.year)
departure = departure.in_time_zone("Central Time (US & Canada)")
When I execute above code on console and see the value, it shows correct converted value. But when I use this variable in below query, current time gets used instead of the departure time.
Model.where("column_name > ? and "column_name < ?, departure - 30.minutes, departure + 30.minutes)
The time used in above query should be the time I want i.e Central time zone, but in query output, it shows UTC being used.
Please let me know what i am missing.
It shouldn't matter what time zone the query uses in the where clause as long as it's the same time representation. The time you're seeing in your query output from Rails is most likely the UTC equivalent of the ruby DateTime object being passed to the where statement. So if departure is 12:00 noon (UTC -6) in your Ruby code then the time shown in the SQL query will be 18:00, which corresponds to noon CST.
From a java.util.Date( a timestamp), how can I get the hour of day?
In joda.time I use getHourOfDay().
There are multiple solutions for this. If you wish to use the Java 8 classes from java.time the following you need to covert a Date to one of the DateTime classes. The following can be used to convert a Date to a ZonedDateTime where you then can get the hour:
Date date = new Date();
// Convert to java 8 ZonedDateTime
Date date = new Date();
final ZonedDateTime dateTime = date.toInstant()
.atZone(ZoneId.systemDefault());
// Get the hour
int hour = dateTime.getHour();
Quite verbose as you have noticed but the simple reason for this is that a Date is sort of an Instant
Despite its name, java.util.Date represents an instant on the time-line, not a "date". The actual data stored within the object is a long count of milliseconds since 1970-01-01T00:00Z (midnight at the start of 1970 GMT/UTC).
Another approach is simply to get the field from a Calendar instance.
final Calendar instance = Calendar.getInstance();
instance.setTime(date);
final int hourOfDay = instance.get(Calendar.HOUR_OF_DAY);
I have two fields in my database for storing starttime and endtime. they are of datetime. I pick time from them using tostring("hh:mm tt"). Now I want to update only the time part of the date. I have dropdownlist to select hour and minutes and AM/PM. How can I update the time of date stored in sql server using Entity framework / LINQ in MVC3 application.
Please suggest
actually you don't really need to touch the linq part of this, basically what you want to do is just to convert the string back to a datetime object and just manipulate the datetime object by either creating a new datetime object or add/minus mm/dd/yy hours or minutes.
You must always update the whole datetime - it means you must build a new DateTime in your application and use correct Date part and defined Time part.
create new DateTime Object
DateTime mydate = New DateTime(2011, 6, 1, 12, 30, 0);
or
DateTime mydate = DateTime.Parse("2011-06-1 12:30:00 PM");
