Converting Time question

[Math]

Me again..
I guess I ask it wrong..
I measure a time at racing events.this tracktime is measures in the format 
hh:mm:ssDDD
where DDD = thousands of a second...like 17:14:11.769
This format is being saved as a number of micro seconds since 1970..
like 1,090516451769E+15
How do I convert from the micros seconds back to time format above?

thanks again
Hope someone can help me out..
