UNIX EPOCH - SYMBIAN EPOCH = ?

[caiannello]

Anyone happen to have this value on hand? usec, msec, or even sec would be fine.

Before you call me lazy, I tried dozens of online javascript calculators, and none seem to appreciate that 0 AD is a valid year. I tried 1AD and worked under the assumption that the value would be 31557600 seconds short, but that wasn't quite right either.

Thanks!

As you are asking this is General Symbian, I wonder what this have to do with Javascript. In Symbian C++ you generally use TTime to get the current time.

Just to add, you can create a TDateTime object for the Unix-0

TDateTime unixstamp(1970,0,0,0,0,0,0);

convert it to TTime

TTime unixtime(unixstamp);

then TTime has various operations, +/-, Seconds/MicroSecondsFrom, etc.
By the way, the TTime you get is actually the difference itself (you can get the number with TTime::Int64).

I'd be interested in hearing which board other than General Symbian C++ would be a more appropriate venue for this question.

Also, while Symbian may use TTime, the rest of the world does not. Its neat that they store datetime internally as the number of microseconds since 1/1/0 00:00, really, but my task is to convert this 64 bit number into a meaningful date in Linux, and I do not have the option of modifying the Symbian code.

I'll do the math myself and post here. I was just hoping someone could save me the trouble.

Which programming language are you using and in with which Nokia programming technology ?

Ok, so far both Jukka and me were thinking that you are developing Symbian C++ code. Now I understand that you are developing some other code which has to handle the output of a Symbian C++ code.
Be back in a couple minutes.

The value seems to be 62168256000000000, which is somehow a bit too "round", but this is what appears in the debugger.
For completeness, the TDateTime line needs EJanuary for month ("TDateTime unixstamp(1970,EJanuary,0,0,0,0,0);").

[caiannello]

Thanks Wizard, that's what I get too. I think the roundness stems from the microsecond units. I should have been more clear in original post, thank you.
