Until very recently MySql only stored time to whole seconds, so Argus has always
stored time as double precision floating point number whose value is "unix time"
which is the number of seconds since 1970-01-01 00:00 UTC.
Mysql will convert this to a datetime value with
select from_unixtime(....)
e.g. for the value in your note below:
select from_unixtime(13876576.76528736);
+----------------------------------+
| from_unixtime(13876576.76528736) |
+----------------------------------+
| 1970-06-10 14:36:16.765287 |
+----------------------------------+
Which looks a perhaps you misplaced the decimal point as
the complementary Mysql function to convert to unix time shows:
select unix_timestamp(now()), from_unixtime( unix_timestamp(now()));
+-----------------------+---------------------------------------+
| unix_timestamp(now()) | from_unixtime( unix_timestamp(now())) |
+-----------------------+---------------------------------------+
| 1386097403 | 2013-12-03 19:03:23 |
+-----------------------+---------------------------------------+
