Convert date to Unix format

Dear Expert

using a script or command if avaliable

Example

Code:

The standard date command on solaris does not handle such conversion, download and intall the GNU date instead :

Code:
# date -d "2011-05-15 18:00:00 UTC" +'%s'
1305482400
# date -d "1970-01-01 00:00:00 UTC + 1305482400 seconds" -u +'%Y-%m-%d %T %Z'
2011-05-15 18:00:00 UTC

This is a questionable advice: it will solve the problem but at the expense of portability. Scripts should be written do expect the common minimum of utilities offered by the OS.

I suggest you take a look at Perderabos datecalc script - probably the last date calculation tool you will ever need.

I hope this helps.

Using ksh93, which is available on Solaris 10 as /usr/bin/ksh93 and on Solaris 11 as /usr/bin/ksh:
Code:
$ printf "%(%s)T\n"  "2011-05-15 18:00:00 UTC"
1305482400
$
