Is there any command to know Offset using TimeZone.

For ex Let us take TimeZone as EST.How can we find the offset using this time zone.

Thanks,
Nagendra.

Code:

TZ=EST date +%z

From the date man page:

Code:

TZ     Specifies the timezone, unless overridden by command line parameters.
       If neither  is  specified,  the setting from /etc/localtime is used.

But when I entered the command

TZ=IST date +%z

Then I got +0000 instead of +530

Thanks,

IST is not a valid timezone. Check under /usr/share/zoneinfo for available timezone names. Sometimes you have to specify the long name of a timezone. For example if IST equals Europe/Dublin:

Code:

$ TZ=Europe/Dublin date +%z
