tz offset dst,Mmwd,Mmwd
Syntax (obligatory):
tz offset
Syntax (optional, only if there is daylight saving time):
dst,Mmwd,Mmwd
m (1 ≤ m ≤ 12)
w (1 ≤ w ≤ 5)
d (0 ≤ d ≤ 6)
LogFileLimit
The size of the system logfile
variable. By entering "Zero", the logfile has no size limitations.
The specified limit is no hard limit for reasons of efficiency but rather a sort of limit value. If
the logfile reaches a limit value times factor 1.5, then it is reduced to around 75% of the limit
value. A check is carried out every two minutes maximum to see if the file has become too
large.
