I am getting a timestamp for current datetime using the following code

public Static String getGenerateTimeStamp()
{
    system.debug('Datetime : '+ DateTime.now());
    system.debug('timestamp : '+ DateTime.now().getTime());
    return String.valueof(DateTime.now().getTime());
}

21:21:46.752 (752692000)|USER_DEBUG|[51]|DEBUG|Datetime : 2014-03-20 10:21:47

21:21:46.752 (752884000)|SYSTEM_METHOD_ENTRY|[52]|System.debug(ANY)

21:21:46.752 (752891000)|USER_DEBUG|[52]|DEBUG|timestamp : 1395310907476

I am passing this timestamps as an part of an API request and it gave out a error message

The timestamp is expressed in the number of seconds since January 1%2C 1970 00%3A00%3A00 GMT. The timestamp value MUST be a positive integer.

On checking with some online convertors the datetime is of a date in 1985. I am not sure if its the getTime() method which is at fault . The timestamp value of 1395310907 seems to give the correct date. I am not sure from where the 476 is getting appended.

The timestamp that salesforce returns are the number of millisecons from January 1 1970, not the number of seconds.

The documentation for getTime() states:

getTime()

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this DateTime object.

You're passing milliseconds into something that is expecting seconds. You could divide 1000 to convert it to seconds.

getTIme() method returns the time in milliseconds.Therefore last 3 digits corresponds to millisecond time. You can get the millisecond by using DateTime.now().millisecond() and then subtract it from DateTime.now().getTime().

  • Or just divide by 1000 – ca_peterson Mar 20 '14 at 19:30
