Commit Message

Log date column should have been 64 bit int

On a 64 bit system the current binary data format stores a long as 8
bytes, the 32 bit integer column in the log table only holds 4 bytes.
4 bytes is not enough to hold early dates (e.g. 1900-01-01) and instead
results in a wrap around (giving dates like 2036-01-01).

This column should have been 64 bit from the start.

Since this change only applies to code used during log file creation
existing log files will need to be manually fixed. The reading code
remains compatible with either log format (pre or post this fix). The
existing log files can still be written to but overflows will occur for
dates that are out of the range:

    datetime.utcfromtimestamp(-2147483648)
    datetime.datetime(1901, 12, 13, 20, 45, 52)

    datetime.utcfromtimestamp(2147483647)
    datetime.datetime(2038, 1, 19, 3, 14, 7)
