Time Machine Oldest/Latest backup field is blank?

[gormond]

Hello,

In Time Machine under the Oldest and Latest Backup fields all it says is "--".

It used to work perfectly fine but today i noticed it was blank, when i go into time machine all the dates are there including the one it done today, just seems to be a display error, Any ideas how to fix this?

Sounds like the backup might have got corrupted.

Can you load the Time Machine application to view your backups?

 

[gormond]

Yeah I Can, I also tried to recover an old deleted file and it worked fine.

Anyone have a clue what could be causing this?

I'm having the same problem

It also just displays "--" in the Oldest and Latest backup field in Time Machine Preferences

But the actual backup still works fine(even though its SO slow over wireless network...[says "preparing" for longer than I can be bothered to time it])

really strange annoying bug

I have the same problem, too.

Possible Solution

I know it's a bit late, but a possible solution can be found here:

essentially it says:
Try to move this file on the desktop (another way of saying, remove it, but don't delete it yet, you never now ...):
HD/Library/Preferences/com.apple.TimeMachine.plist

I found this solution posted on the Apple Support forums:

1. Open Time Machine in System Prefs

2. Click "Change Disk" and select "None" as the Backup

3. Immediately reselect previous backup disk (and slide the "Off/On" tab back to "On"

4. A backup will be run automatically...in my case, 22mb so it was quick

5. Life is good again, Latest Backup date properly displayed
