Title: lha preserve dir timestamp
Post by: orange on January 23, 2014, 12:33:06 AM

when I unpack .lha, all directories seem to have 'today' timestamp. is there  a way to restore original time?

I use ReDate. (http://aminet.net/package/util/cli/ReDate)

but there must be a way to modify archive, while preserving dates?
lha does store dir timestamp (when listing), it just doesn't use it when unpacking, for some reason.

It does use it. The problem is the order in which changes are done and that the file system updates the dir's time stamp when a file is added to it.

Lha does

makedir drawer
setdate drawer
store drawer/file1 <- this changes the drawer's date to today.
setdate drawer/file1

and so on.

Lha should set date of drawer when it leaves it, not when it enters it.

Can only be changed by the author. Send him a bug report.

thanks Thomas.
in case bug report is ignored, could this step:
"store drawer/file1 <- this changes the drawer's date to today."
be modified in OS, so the drawer's date isn't changed?

Yes, but the OS isn't maintained any more since almost 20 years. I am quite sure that *this* bug report will be ignored for sure. Not to mention that this breaks functionality which other programs might rely on.

Just for curiosity, if you browse into archive under MorphOS and copy contents that way, dates on directories are preserved. But I haven't found other way to preserve them.. yet. Browsing with XADopus under Magellan or unpacking with XAD command line tools don't preserve them either.

Never be so sure.  A few days ago I sent a bug report to the author of "Matrix" blanker (regarding incompatibility with the latest release of Picasso96), and was quite surprised to receive a response back from him.  Of course he said he'd stopped development nearly a decade ago but he mentioned that if he's able to access his old disks he'd release the source code.  So you never know, and I was happy to give him a blast of nostalgia, LOL.  :biglaugh:
