Please?

Perhaps you could tell us what date and time 212099016004150509 is
supposed to represent? The classic format is "seconds since the Unix
epoch" but that isn't what this is:

>>> time.localtime(212099016004150509)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: timestamp out of range for platform time_t

Neither does it appear to be a MySQL TIME field, since the maximum value
for that would appear to be

>>> ((838*60)+59)*60+59
3020399

So, just what is this field? What do the values mean?

 Steve
