Try dividing by 60 to get your hours an then use the mod operator to get the remaining minutes.

$x/60 for hours

$x%60 for minutes

141/60 = 2

141%60 = 21

Hope this helps….  I am sure there are other ways….

[David Harrison]

That’s a lot easier than the way I eventually came up with.

Thanks

Thanks for that Robert.

I presume the gmt flag just says ignore local time zone so it will always work no matter what timezone you happen to live in.

[Robert Milfajt]

Yes, but in a roundabout way.  With -gmt, if the next argument is false says use local time, else use GMT.

Did that work for you?  I did learn the UK has only one time zone, which is GMT, which sort of puts a wrench in my logic.  However, if you are on a machine that did not flip from standard to savings time, or vice versa, it may explain why you were an hour off.

Cheers,

Bob

The CIA World Factbook lists the comparative size of the United Kingdom as ‘slightly smaller than Oregon’, so yes, we only have one timezone.

We are currently in British Summer Time (BST) which is one hour ahead of GMT so I suppose that accounts for the extra hour.

Hi David,

What happens if you don’t happen to know how big Oregon is?

Shouldn’t clock format pick up the local settings on the server and use these when doing this type of calculation? Or is this only true when getting a date/time directly rather than doing a calculation?

I haven’t tested this but that’s how I thought it worked.

Regards

Garry

Garry,

Easy, Oregon is slightly bigger than the UK!

My understanding is that the local settings will be bypassed if you use the -gmt flag. This is what I wanted to do – just to convert a number of minutes into hours and minutes, not time.

Regards,

Dave
