Yep, something certainly going on with timestamps on today's bits. I get this trace from BugSack:
[2006/09/08 21:53:37-261]: idChat2_Timestamps\idChat2_Timestamps.lua:125: bad argument #3 to `format' (string expected, got nil)
<in C code>: in function `format'
idChat2_Timestamps\idChat2_Timestamps.lua:125: in function <...ace\AddOns\idChat2_Timestamps\idChat2_Timestamps.lua:124>
SheepWatch\SheepWatch.lua:606: in function `SheepWatch_SetTimerLength'
SheepWatch\SheepWatch.lua:668: in function `SheepWatch_LoadVariables'
SheepWatch\SheepWatch.lua:167: in function `?'
SheepWatch\SheepWatch.lua:156: in function `SheepWatch_OnEvent'
<string>:"SheepWatch:OnEvent":2: in main chunk
If I get a chance I will look for it, but since it doesn't seem to crash anything, I'm just ignoring it for now.
