Summary 0000169: date utility needs ``%s''
Description There is currently no simple way, short of writing a C program, to obtain the "seconds since the epoch", commonly referred to as "Unix time". I would like to request the date utility be extended to include an additional conversion specification of:

 %s seconds since 1970-01-01 00:00:00 UTC (see XBD Seconds Since the Epoch)
Desired Action Add the new conversion specifier
Tags No tags attached.

 If the proposed change to date is made, we should also add %s to
strftime() and strptime() for consistency.

Although it would be kind-of redundant for those functions (being
equivalent to mktime() and localtime() respectively, plus conversion
to/from a string) it would be usable in user-supplied/configured
format strings.

The detailed changes needed would be ...
After line 82902 add:

    %s   Seconds since 1970-01-01 00:00:00 UTC as a decimal number
         (see [xref to XBD 4.15 Seconds Since the Epoch])

Cross-volume changes to XSH:

After page 2009 line 63596 section strftime, add:

[CX]s    Replaced by the number of seconds since 1970-01-01 00:00:00 UTC
         as a decimal number (see [xref to XBD 4.15 Seconds Since the
         Epoch]). [all members, as if by a call to mktime()] [/CX]

After page 2027 line 64161 section strptime, add:

    s    The number of seconds since 1970-01-01 00:00:00 UTC as a
         decimal number (see [xref to XBD 4.15 Seconds Since the
         Epoch]); leading zeros shall be permitted but shall not be
         required.
