Force timezone initialization before filter installation
Force timezone initialization before filter installation

The first use of time.Local (usually via time.Time.Date, et. al) performs
initialization of the local timezone, which involves open several tzdata files
from the host.

Since filter installation disallows open, we should explicitly force this
initialization rather than implicitly depending on the first logging (or other
time) call occurring before filter installation.
