Long to timestamp for historic data (pre-1900s)

I have a database of start and stop times that have previously all had fairly recent data (1960s through present day) which i've been able to store as long integers. This is very simialr to unix timestamps, only with millisecond precision, so a function like java.util.Date.getTime() would be the value of the current time. This has worke...

The only requirement is that I can pull (and decompress) the first number on the list to work with, whithout touching the rest of the list. I have many good ideas but most of them translate the numbers to bits. Example: ...
