 The '{{{ctime}}}' and '{{{mtime}}}' attributes will always be the same, and are set from the Tahoe {{{linkmotime}}} timestamp, which is changed only when the link from the parent directory is modified (see the [http://tahoe-lafs.org/trac/tahoe-lafs/browser/docs/frontends/webapi.rst#about-the-metadata 'About the metadata' section of webapi.rst]). These fields are not updated when the contents of a mutable file are changed. The SFTP protocol and the server are able to represent dates up to the year 2106, but some clients may print dates incorrectly after 2037.
 
-Versions of Twisted up to and including 10.2 have [http://twistedmatrix.com/trac/ticket/4395 a bug in support for rekeying]. This might cause a hang or 100% CPU usage by the gateway when a client tries to rekey. Depending on the client, rekeying may be triggered based on a time interval or the amount of data sent (for example, 1 GiB to 4 GiB for the openssh client); this problem will typically only affect long-lived connections or very large files. Some clients have options to disable rekeying:

Some clients have options to disable rekeying:
 * for OpenSSH and sshfs, either use the option {{{-o RekeyLimit=0}}}, or add the line {{{RekeyLimit=0}}} to {{{~/.ssh/config}}} (TODO: please test this!)
 * for WinSCP, [#WinSCP see that section below].
