Description:
------------
The fpm status page contains an item "start time". It is shown in the text view as (example):

start time:           24/Mar/2015:14:18:15 +0100

In the json and xml views (short and full) it is shown as:

<start-time>%s</start-time>

resp.

{...,"start time":%s,...}

Instead of the correct time a verbatim "%s" is shown.

This is due to fpm_status.c setting

time_format = "%s";

in the xml and json case, but to

time_format = "%d/%b/%Y:%H:%M:%S %z";

in the text and html case. This format is then used in strftime(), e.g.

strftime(time_buffer, sizeof(time_buffer) - 1, time_format, localtime(&proc.start_epoch));

Unfortunately "%s" is not a correct strftime format pattern, so strftime does not format the time but instead returns the verbatim "%s" pattern.

Please replace 

time_format = "%s";

by

time_format = "%d/%b/%Y:%H:%M:%S %z";

or something else that formats correctly and returns valid xml and json data.

The bug applies to the current master branch and also to 5.6, 5.5 and 5.4.

Thanks a bunch!
