What is wrong with `Date.parse` method? 

    str = &quot;Tue, 10 Aug 2010 01:20:19 -0400 (EDT)&quot;
    date = Date.parse str
    =&gt; #&lt;Date: 4910837/2,0,2299161&gt;
    puts date
    2010-08-10

It seems to work.

The only problem here is time zone. If you want date in UTC time zone, then it is better to use `Time` object, suppose we have string:

    str = &quot;Tue, 10 Aug 2010 01:20:19 +0400&quot;
    puts Date.parse str
    2010-08-10
    puts Date.parse(Time.parse(str).utc.to_s)
    2010-08-09

I couldn&#39;t find simpler method to convert `Time` to `Date`.

    Date.strptime(updated,&quot;%a, %d %m %Y %H:%M:%S %Z&quot;)

Should be:

    Date.strptime(updated, &#39;%a, %d %b %Y %H:%M:%S %Z&#39;)



    str = &quot;Tue, 10 Aug 2010 01:20:19 -0400 (EDT)&quot;
    str.to_date
    =&gt; Tue, 10 Aug 2010
    

You can try https://rubygems.org/gems/dates_from_string:

Find date in structure:

    text = &quot;get car from repair 2015-02-02 23:00:10&quot;
    dates_from_string = DatesFromString.new
    dates_from_string.find_date(text)

    =&gt; [&quot;2015-02-02 23:00:10&quot;]

I&#39;ve just made the switch from MS sql server to Oracle.  The query tool I am using is Oracle SQL Developer.  The problem I am having is that I cannot get the query results window to stick around. The query results window being the Grid view for the results.  It seems to show up arbitrarily when I open a new &quot;sql worksheet&quot;.  But not always.  Then once I run a query, it disappears the next time I run one.

Can anyone point me to a consistent way to leave this results grid active? Thanks so much.

Instead of going JSON a json string and using $.parseJSON, I need to take my object and store it in a variable as string representing JSON.

(A library I&#39;m dealing with expects a malformed JSON type so I need to mess around with it to get it to work.)

What&#39;s the best way to do this?

I&#39;ve been working a lot with the [`DateTime class`][1] and recently ran into what I thought was a bug when adding months.  After a bit of research, it appears that it wasn&#39;t a bug, but instead working as intended.  According to the documentation found [here][2]:

    

&gt; Example #2 Beware when adding or
&gt; subtracting months

    &lt;?php
    $date = new DateTime(&#39;2000-12-31&#39;);
    
    $date-&gt;modify(&#39;+1 month&#39;);
    echo $date-&gt;format(&#39;Y-m-d&#39;) . &quot;\n&quot;;
    
    $date-&gt;modify(&#39;+1 month&#39;);
    echo $date-&gt;format(&#39;Y-m-d&#39;) . &quot;\n&quot;;
    ?&gt;

&gt;     The above example will output:
&gt;     2001-01-31
&gt;     2001-03-03

Can anyone justify why this isn&#39;t considered a bug?

Furthermore does anyone have any elegant solutions to correct the issue and make it so +1 month will work as expected instead of as intended?

How to get the time for a given `datetime` value?

I have a `datetime` in database like this:

and want only the time portion: 

    17:07:28.170

Is there a function for that or something?



Get the time of a datetime using T-SQL?

I&#39;ve created this script to calculate the date for 10 days in advance in the format of dd/mm/yyyy:

    var MyDate = new Date();
    var MyDateString = new Date();
    MyDate.setDate(MyDate.getDate()+10);
    MyDateString = MyDate.getDate() + &#39;/&#39; + (MyDate.getMonth()+1) + &#39;/&#39; + MyDate.getFullYear();

I need to have the date appear with leading zeroes on the day and month component by way of adding these rules to the script. I can&#39;t seem to get it to work.

    if (MyDate.getMonth &lt; 10)getMonth = &#39;0&#39; + getMonth;

and

    if (MyDate.getDate &lt;10)get.Date = &#39;0&#39; + getDate;

If someone could show me where to insert these into the script I would be really appreciative.

                     tm_sec=54, tm_wday=6, tm_yday=255, tm_isdst=0)

Is there an elegant way to initialize a `datetime.datetime` object in the same way?
