This class represents time values in milliSeconds starting some time in the past,
|
|
|
40 |
which were created in another (explicit) timezone.
|
|
|
41 |
Internally, they keep the milliseconds based on UTC time (just like the other timestamps),
|
|
|
42 |
so the time values can be compared easily.
|
|
|
43 |
However, wehn printed, the original timezone information is taken into account.
|
|
|
44 |
|
|
|
45 |
Also Note:
|
|
|
46 |
On UNIX, osTime can only hold dates between 1970-01-01T00:00:00Z and 2038-01-19T00:00:00Z
|
|
|
47 |
However, timestamp instances can now hold negative osTime values (which are timestamps
|
|
|
48 |
before 1.1.1970 and greater than 4294967295 (2^32-1) for timestamps after 2038-01-19.
