If you check the k.h file you will find that timestamp is stored as long long.

 

HTH,

Betreff: [personal kdb+] How are nanosecond timestamp stored by kdb

 

Hi guys,

I was wondering, as nano-second time are a built-in type in kdb, how is it stored internally ?

A time is stored in four bytes and is denoted by hh:mm:ss.uuu (as per http://code.kx.com/wiki/JB:QforMortals2/atoms#time), but what about nanos ?

Is it using 64bits int ?

 

Regards

not the easiest thing to find!

it made me realize the power of two when i worked out for how long you
can increment a 64 bit register before hitting the start value
