JS timestamp and date format convert each other

Timestamp: is a time representation, defined as the total number of seconds from GMT January 01, 1970 00:00 00 seconds to the present. Unix timestamps are used not only in UNIX systems, Unix-like systems, but also in many other operating systems.

1. Convert Timestamps to date formats

1 //a simple line of code2 varDate =NewDate (timestamp);//gets a Time object3  4 /**5 1. Here's how to get the time and date, what kind of format you need to stitch it up .6 2. More useful methods can be found here, http://www.w3school.com.cn/jsref/jsref_obj_date.asp7  */8Date.getfullyear ();//Get the full year (4-bit, 1970)9Date.getmonth ();//get the month (0-11, 0 for January, remember to add 1 when using)TenDate.getdate ();//Get Day (1-31) OneDate.gettime ();//Get time (number of milliseconds starting from 1970.1.1) ADate.gethours ();//gets the number of hours (0-23) -Date.getminutes ();//gets the number of minutes (0-59) -Date.getseconds ();//gets the number of seconds (0-59)

1 //For example, you need this format YYYY-MM-DD hh:mm:ss2 varDate =NewDate (1398250549490);3Y = date.getfullyear () + '-';4M = (Date.getmonth () +1 < 10? ' 0 ' + (date.getmonth () +1): Date.getmonth () +1) + '-';5D = date.getdate () + ";6h = date.gethours () + ': ';7m = date.getminutes () + ': ';8s =date.getseconds ();9Console.log (Y+m+d+h+m+s);//Yes, hemp disc .Ten //output Result: 2014-04-23 18:55:49

2. Convert date format to timestamp

1 //It 's simple, too .2 varStrtime = ' 2014-04-23 18:55:49:123 ';3 varDate =NewDate (strtime);4 //Pass in a time format, if not passed is to get the current time, this does not compatible with Firefox. 5 //can do this6 varDate =NewDate (Strtime.replace (/-/g, '/')));7  8 //There are three ways to get, and in the back there will be three different ways9Time1 =date.gettime ();TenTime2 =date.valueof (); OneTime3 =Date.parse (Date); A   - /*  - three ways to get the difference: the First, second: accurate to milliseconds - The third type: Only accurate to the second, milliseconds will be replaced by the - For example, the result of the above code output (the difference can be seen at one glance): - 1398250549123 + 1398250549123 - 1398250549000 + */

3. The Date () parameter is in the form of 7

1 New Date ("Month dd,yyyy hh:mm:ss"); 2 New Date ("Month dd,yyyy"); 3 New Date ("Yyyy/mm/dd hh:mm:ss"); 4 New Date ("Yyyy/mm/dd"); 5 New Date (YYYY,MTH,DD,HH,MM,SS); 6 New Date (YYYY,MTH,DD); 7 New Date (MS);

Like what:

 1  new  Date ("September 16,2016 14:15:05 " 2  new  Date ("September 16,2016"  3  new  Date ("2016/09/16 14:15:05"  4  new  Date ("2016/09/16" );  5  new  Date (2016,8,16,14,15,5); //  month from 0~11  6  new  Date (2016,8,16  7  new  Date (1474006780);
