How can I transfer photos to my Android Jelly Bean device while preserving the original timestamp?

I recently bought a Nexus 4 and I would like to transfer my photos of my previous device to it. My previous Android phone used the standard USB mass storage which gave 0 problems to copy back and forth stuff, but the Nexus 4, like many other modern Android phones I suppose, uses MTP instead, which has the interesting feature of refusing to copy the original dates/timestamps of the files, using instead the date at which the files are being copied. This is obviously a huge bummer when it comes to photos; not only because one cannot check the original date at which the picture was taken while browsing on the phone, but also because they end up completely unsorted. Is there a way to transfer photos to a Jelly Bean Android phone that doesn't support USB mass storage preserving the original timestamps? Things I've tried so far: - Transferring via USB MTP - ADB push (both full folders and individual files) - Transferring via SSH (using SSHDroid + WinSCP) - Uploading and downloading from Dropbox - Transferring a ZIP file via MTP and uncompressing the file on the phone - Transferring from the other phone via Bluetooth None of them preserved the timestamp, and this is driving me insane. (Also, I am not rooted yet, but if the only viable way requires root I would welcome that answer as well.)
