Scott Phillips updated DS-1062:
-------------------------------

    Attachment: Subscribe.java.patch

This patch was developed by Alexey Maslov at A&M to solve the date subscription 
issue. With this patch the subscription cron job may be run at any time because 
the correct calculation of timezone offsets is used through the Calendar object.
                
> Subscription email reports new items twice, sometimes.

> There is currently a bug in the collection subscription feature caused by an 
> oversight in date-time calculation. It manifests itself by erroneously 
> include the same item in multiple daily mailings, i.e. an item submitted 
> yesterday would appear in emails sent both today and tomorrow. The specific 
> issue was caused by converting the current datetime from default timezone to 
> UTC, then truncating the time and timezone offset information. Since the bug 
> involves the offset of the local timezone from UTC, the effects of this bug 
> are more significant the farther away from UTC time. It is possible to 
> mitigate the effect by changing the time of the subscription cron job to be 
> later than the UTC offset.
