OPTIMIZATION
|
|
27 |
- Replace the switch with a function that should be called for each
|
|
28 |
date type.
|
|
29 |
- Remove sprintf and opencode the conversion, like we do in
|
|
30 |
Field_datetime.
|
|
31 |
||
32 |
The reason for this functions existence is that as we don't have a
|
|
33 |
way to know if a datetime/time value has microseconds in them
|
|
34 |
we are now only adding microseconds to the output if the
|
|
35 |
value has microseconds.
|
|
36 |
||
37 |
We can't use a standard make_date_time() for this as we don't know
|
|
38 |
if someone will use %f in the format specifier in which case we would get
|
|
39 |
the microseconds twice.
