Webdav root '': Fs supports modtime, but modtime is missing

Help and Support

What is the problem you are having with rclone?

This is a follow-up from this post.

bisync seems to be working when I do

rclone bisync S20-FE-WebDAV: /local/path/Samsung-S20-FE/ -vv --progress

If I switch src and dest, then bisync will sync some of the same files every time and gives some of the output listed below. I still need to check the modtimes for these specific files to see if they are somehow incorrect and investigate them to see if there are other anomalies.

. I would mostly like to understand 2 things:

  • The difference between bisync src dest and bisync dest src
  • NOTICE: webdav root '': Fs supports modtime, but modtime is missing

Run the command 'rclone version' and share the full output of the command.

On laptop

rclone v1.74.4
- os/version: ubuntu 20.04 (64 bit)
- os/kernel: 5.4.0-192-generic (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.26.5
- go/linking: static
- go/tags: none

On phone

rclone v1.75.0-termux
- os/version: unknown
- os/kernel: 4.19.113-27223811 aarch64)
- os/type: android
- os/arch: amd64 (ARMv8 compatible)
- go/version: go1.26.5
- go/linking: dynamic
- go/tags: noselfupdate

Which cloud storage system are you using? (eg Google Drive)

rclone serve webdav in Termux

The command you were trying to run (eg rclone copy /tmp remote:tmp)

From my laptop

rclone bisync S20-FE-WebDAV: /local/path/ -v --progress
rclone bisync /local/path/ S20-FE-WebDAV:/ --dry-run --progress

Please run 'rclone config redacted' and share the full output. If you get command not found, please make sure to update rclone.

[S20-FE-WebDAV]
type = webdav
url = http://192.168.0.100:8080
vendor = rclone

A log from the command that you were trying to run with the -vv flag

webdav root '': Fs supports modtime, but modtime is missing

This only happens with

rclone bisync /local/path/ S20-FE-WebDAV:/ --dry-run --progress

I also see

2026/08/02 11:18:41 DEBUG : Android/.Trash/com.sec.android.gallery3d/9067676529622303932.jpg: Excluded
2026/08/02 11:18:41 DEBUG : Android/.Trash/com.sec.android.gallery3d/916405891440345997.jpg: Excluded (FilesFrom Filter)

with rclone bisync /local/path/ S20-FE-WebDAV:/ --dry-run --progress
but not with

rclone bisync S20-FE-WebDAV: /local/path/ -v --progress

I have not set up any exclude files.

Could anyone give me some insight as to where the modtime is missing error comes from or the Excluded and FilesFrom Filter comes from?

Termux is known to have issues with times.
FYI Rclone WebDAV server (Termux) logs stat errors after file operations
