date command

Expand Post »
HI Guys,

Prob a very simple one but im stumped, I run the following command and get:

Shell Scripting Syntax (Toggle Plain Text)
  1. date
  2. Wednesday, 19 August 2009 09:20:59 BST
But when I run
Shell Scripting Syntax (Toggle Plain Text)
  1. date -u '+%y%m%d.%H:%M:%S'
  2. 090819.08:21:27

My question is why is the second command an hour behind? In my environment the following are set:
Shell Scripting Syntax (Toggle Plain Text)
  1. LC_TIME=en_GB.ISO8859-15
  2. TZ=GB
I have tried it on a different server with exactly the same commands and env variables and get the correct result, what am I doing wrong here?

Re: date command

Great Britian has summer daylight savings time which means your clock is off by an hour.

Re: date command

hi,

But why does the date command give me the correct date then when I try and use the date -u command does it suddenly consider day light savings?

Re: date command

Please see this site:

It doesn't make sense to me either but it seems like that is probably a law in GB.

Re: date command

I have worked it out have used:
Shell Scripting Syntax (Toggle Plain Text)
  1. `date +"%Y.%m.%d.%H%M"`
Instead of date -u

Re: date command

Actually, the below command gives the time as per GMT :
Shell Scripting Syntax (Toggle Plain Text)
  1. date -u

where as on using
Shell Scripting Syntax (Toggle Plain Text)
  1.  date
, we get the time according to what we have set our time zone (TZ) as.
