Unix Timestamps
Hi,
is it possible to print a unix timestamp, i.e. seconds since 1970 in the
PatternLayout (or any other layout)? Optimally I would like a fractional
pattern showing microseconds.
Apparently log4j 2 has a "%d{UNIX}" pattern, but this just prints "UNIX"
in log4cxx. I am using the ubuntu liblog4cxx10, but I also tried the
latest svn version.
Thanks and best regards,
Felix

It's actually not about timezone handling. With timestamp I meant
something like "1480614212.833892332", which is commonly used on unix,
at least the integer seconds part.

I guess Robert Middleton's answer works for me. I may look into the
classes you mention for microseconds though.
Thanks,
Felix

In the man page you linked to I found
*%s *The number of seconds since the Epoch, 1970-01-01 00:00:00
+0000 (UTC). (TZ) (Calculated from/mktime(tm)/.)
There is nothing under a second, so I combine it with %d{SSS}:
log4j.appender.R.layout.ConversionPattern=[%p] [%d{%s}.%d{SSS}]: %m%n
> [INFO] [1480614023.833]: message
Works for me :-)
Thank you so much!
Felix

If I'm understanding the code correctly, in your %d{} specifier, you can
define a custom format using apr_strftime(). I'm assuming that this means
you can use the standard strftime() specifiers, but the documentation for
APR is somewhat lacking.

Is your question about the format or timezone handling? A format
including fractionals is possible and the default already when only
using "%d", but I'm pretty sure it's not supporting microseconds:

Have a look at the classes datepatternconverter, strftimedateconverter
and simpledateformat, which is used depending on your configuration
and might support timezone related stuff. At least there some "Z"
mentioned in simpledatformat, resulting in a calculation of timezone
offsets in "RFC822TimeZoneToken".
Mit freundlichen Grüßen,
