Hi,

I have a date format of yyyy-MM-dd-HH.mm.ss.SSSSSS and need to convert it to yyyy-MM-dd HH:mm:ss.S

but say when i pass the date 2010-02-16-23.59.59.999000 i m getting the formated date as 2010-02-17 00:16:38.000

This I think is due to the different TIMEZONE. You can look at the SimpleDateFormat API to see the format for specifying the Timezone.

Milliseconds is always three digit. Even if "SSSSSS" is given

[Mohamed Sanaulla]

I told suggested to check with TIMEZONE as there was a difference between the 2 dates (~16 minutes if I am not wrong).

Update: and it looks like a difference of 1 day

Prakash is right. You probably expect the 999000 to be read as 999, but it is read as 999000, then truncated to 0 (999000 % 1000 == 0).

But why is the date incrementing by 1 day.

[Prakash Krsihnan]

If you convert "999000" ms to minute it comes to 17:38 and it added to date.
It advisable to use only SSS or S. Don't use more than three S for microseconds

Oh nice catch. It struck to me as a TIMEZONE issue.

So I was wrong - the 999000 isn't truncated at all but added as additional milliseconds.
