I've tried tweaking this macro to also change the date - I succeeded, but only if 12/31/69 is my desired date.

Can you give me a pointer on how to accomplish that? I'm sure it's relatively simple, but I'm new on Onetastic and not up to speed on the inner workings.

Thanks

Ok I fixed the issue without going into much deeper
on our code line 20:   <Param name="count" value="10" />
This removing the complete datetime format from datetime string and causing 30 added minute in my case. setting <Param name="count" value="13" /> will fix the issue.
Btw I'm in timezone +5:30 :)

From log........
Modifying property(dateTime) = 2015-02-21T08:15:59.000Z (time) -- set -- variable(dateTime) = 2015-02-21T09:00:59.000+05 (string)
  New value: 2015-02-21T04:00:59.000Z (time)

I am noticing an issue, assuming property only takes 000Z as timezone but I'm in +5 zone so as per my entered time New Value of property(datetime) should be 2015-02-21T03:30:59.000Z (time). Somehow it's not converting +5 to GMT properly.
How about if I subtract 30 Minutes from generated GMT.

whenever I'm entering a time minutes getting 30 minutes added. if I enter 03:06, it appearing as 03:36.
Please fix it.
A 12h option would be useful.

It does change the page time by 2 hours from what you enter.

I see no value of this macro as you can change the time by clicking on the displayed time of the page and changing with your mouse.

very nice macro as usual omer! would it be difficult to implement an AM/PM drop-down menu or something similar for those of use 24-hour format-impaired? ;)

Thanks :)

Thanks, but when I enter a time, the timestamp of the hour gets updated to the time minus 2 hours.

Thus: setting the time to 12:34 results in a page time of 10:34

Maybe you can fix it... :)
Thanks
