Issue with Daylight Saving Time

[SirMartin]

Hello,

I just found an issue today, this weekend we changed the hour (Daylight Saving Time), and I just found that of course now my Maloja instance works 1 hour behind, I can change the UTC offset, but this makes errors with all the previous ones, and I think will start at change stats for each week, day, etc, that is not a very good practice.

Probably Maloja should be able to work with a Timezone, and just continue from them. Is not something critical, but, it would be a very nice feature.
