Aggregations: Be lenient when converting local to utc time in time zone roundings 

This solves a problem in the time zone rounding classes where time dates that
fall into a DST gap will cause joda time library to throw an exception.
Changing the conversion methods 'strict' option to false prevents this.

Closes #10025
