gawk and strftime()

Strange behaviour of the strftime() function from gawk (3.1.5): $ awk 'BEGIN{print strftime("%T", 3600)}' > 02:00:00 $ awk 'BEGIN{print strftime("%T", 0)}' > 01:00:00 Obviously something with DST but I can not figure out why? To me 3600 epoch seconds remains 01:00, DST or not. From...

pmdate

PMDATE(1)						      General Commands Manual							 PMDATE(1)

NAME

       pmdate - display an offset date

SYNOPSIS

       pmdate [ offset ... ] format

DESCRIPTION

       pmdate displays the current date and/or time, with an optional offset.

       An offset is specified with a leading sign (``+'' or ``-''), followed by an integer value, followed by one of the following ``scale'' spec-
       ifiers;

       S      seconds
       M      minutes
       H      hours
       d      days
       m      months
       y      years

       The output format follows the same rules as for date(1) and strftime(3).

       For example, the following will display the date a week ago as DDMMYYYY;
	       pmdate -7d %d%m%Y

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP.  On  each	installation,  the
       file  /etc/pcp.conf contains the local values for these variables.  The $PCP_CONF variable may be used to specify an alternative configura-
       tion file, as described in pcp.conf(5).

SEE ALSO

       date(1), strftime(3), pcp.conf(5) and pcp.env(5).
