So, it indeed looks like 32bits

IK Hello,
IK It seems that at least under windows there are rounding problems with the
IK milliseconds:
IK sqlite select strftime(%f, 2005-01-01 12:34:55.122);
IK 55.121

IK Is this maybe a problem of the underlying c-library?

Before binding an address to a statement using sqlite3_bind_int64() I apply an
offset to the address to translate it to a signed value. And when reading out
an address using sqlite3_column_int64() I reverse the process. I.e.
dbase_value = addr_value - offset
addr_value = dbase_value
The actual test I'm doing is something like:
WHERE ?1 = (base + begin) AND ?1 (base + end)
where ?1, base, begin, and end are all 64-bit addresses.
This is a test with a well known optimization for unsigned values:
WHERE (?1 - base - begin) end
To make the test unsigned in SQL

So, my question is, true or false:, if I want to use
SQLite's date/time functions against field values, my only
real option is to store -MM-DD HH:MM:SS time strings.
Any other value, whether MMDD, julian day number,
create table each_transaction(datetime int);
insert into each_transaction values( datetime('%s', 'now'));
Perhaps you should say
insert into each_transaction values( strftime('%s', 'now'));
