Isn't the name of the log file a little too verbose? Don't know if I'm
missing something but this doesn't seem so useful for long running
application that use logging. As far as I know you usually have one log
file per application and outputs the message along with the level and
date and time.
I did what glog does. Going forward, there is a private static string
for formatting file names using positional parameters. In the future I'm
considering providing an API for changing that format string, which
means the log file format will be user-definable. (Same about the format
of individual messages - see the string constants fileNameFormat and
format toward the top of log.d.) Positional parameters look a bit odd
but they are quite flexible.

Excuse me for asking again but to me it seems that the log functions
will output a new file for every log event (since the time is included
in the filename). Is that the case?
No, log files are created and opened only once, and the time in the
filename reflects the creation time. Logging messages also contain the
time (with added precision) and go to the respective files. A maximum of
five files are created. (No support for rotating logs for the time being.)
There's one difference from glog by the way - glog defines four levels
and consequently four files: info, warning, error, and fatal. I defined
critical in between error and fatal. Logging to the critical log throws
an exception right after logging. I think this is very useful for
figuring out what happens in exceptional code.
