java - String to Date conversion is losing time -

does know why date losing time values when converting string ? cannot seem figure 1 out.

here type of simpledateformat using:

 simpledateformat simpledateformat = new simpledateformat("eee mm/dd/yyyy hh:mm a"); 

the date trying convert string in form :

 string datestring = "mon 06/23/2014 03:00 pm"; 

and when following:

    date convertdatefromstring = null;     try{           convertdatefromstring = simpledateformat.parse(datestring);     }catch(parseexception ex){         ex.printstacktrace();     }     system.out.println(convertdatefromstring.gettime()); 

my output is: 1403496000000

and expected output is: 1403550000000

can me understand why time not being parsed?

update - solved --->> of jon skeet

now using simpledateformat

 simpledateformat simpledateformat = new simpledateformat("eee mm/dd/yyyy hh:mm a", locale.getdefault()); 

and output correct.

you've specified hh in format, 24-hour format. you've also got am/pm designator.

as such, "03:00 pm" doesn't make sense - it's simultaneously trying represent 3am (03 in 24 hours) , 3pm (pm in data).

it sounds want hh in format string, 12-hour specifier.

that's part of problem. next time zone. expected value (1403550000000) represents 2014-06-23 19:00:00z. presumably you're expecting use time zone 4 hours behind utc.

your actual value (1403496000000) @ moment 2014-06-23 04:00:00z... appears being parsed in time zone 1 hour behind utc.

you need work out time zone data meant in, , specify explicitly in simpledateformat.
