|
|---|
| 5 | Informally speaking:
|
|---|
| 6 | bzip2 is a compression program built on top of libbzip2,
|
|---|
| 7 | a library which does the real work of compression and
|
|---|
| 8 | decompression. As far as I am aware, libbzip2 does not have
|
|---|
| 9 | any date-related code at all.
|
|---|
| 10 |
|
|---|
| 11 | bzip2 itself copies dates from source to destination files
|
|---|
| 12 | when compressing or decompressing, using the 'stat' and 'utime'
|
|---|
| 13 | UNIX system calls. It doesn't examine, manipulate or store the
|
|---|
| 14 | dates in any way. So as far as I can see, there shouldn't be any
|
|---|
| 15 | problem with bzip2 providing 'stat' and 'utime' work correctly
|
|---|
| 16 | on your system.
|
|---|
| 17 |
|
|---|
| 18 | On non-unix platforms (those for which BZ_UNIX in bzip2.c is
|
|---|
| 19 | not set to 1), bzip2 doesn't even do the date copying.
|
|---|
| 20 |
|
|---|
| 21 | Overall, informally speaking, I don't think bzip2 or libbzip2
|
|---|
| 22 | have a Y2K problem.

|
|---|
| 26 | regarding Y2K issues in my software. You alone assume the
|
