Original install method (e.g. download page, yum, from source, etc.):

Description of the problem including expected versus actual behavior:
When using the "Day So Far" interval picker in time lion in Europe. The day starts at 02:00 and not 00:00 as it is in the other panels of kibana. The 02:00 comes from my time zone, so it looks like the timezone is not taken into account in Timelion.

Steps to reproduce:
Go to timelion in a non UTC timezone and select Day So Far.

Errors in browser console (if relevant):

Provide logs and/or server output (if relevant):
