This is a Timestamp, that represents itself as UTC. |
|
| 13231 | 41 |
Internally it stores exactly the same value as Timestamp, |
| 15828 | 42 |
so the following expression is always true: |
| 13231 | 43 |
|
44 |
someTimestamp asUtcTimestamp = someTimestamp asLocalTimestamp |
|
45 |
||
46 |
But when printing, accessing hour, minute, ... and converting to Date and Time, |
|
47 |
it returns the values represented in the UTC zone instead of the local timezone. |
