Re: [Architecture] [Analytics] Using UTC across all temporal analytics functions

Hi Inosh, If epoach time is received to the server I don't understand the limitation? Is it because Siddhi time window doesn't operate in UTC time? Cheers~ On Tue, Jun 14, 2016 at 7:00 AM, Inosh Goonewardena wrote: > Hi Sajith, > > > On Tue, Jun 14, 2016 at 12:21 PM, Sajith

Re: [Architecture] [Analytics] Using UTC across all temporal analytics functions

Hi Inosh, In order to do this we might probably need to update the data publishers to send their time zones as meta data to do the time zone conversion. In cases like daylight saving changes this information will be required to correctly map the incoming time to UTC Also, isn't it an option

+1, yes... We can extend Siddhi Time functions to allow timezone as a parameter.. Will do that.. On Mon, Jun 13, 2016 at 7:13 PM, Ruwan Abeykoon wrote: > Hi All, > +1 on storing time in UTC. > > However this will cause some minor (but annoying) discrepancies to occur > when

Re: [Architecture] [Analytics] Using UTC across all temporal analytics functions

Hi All, +1 on storing time in UTC. However this will cause some minor (but annoying) discrepancies to occur when we do windowing on "per-hour" basis, when the time zone difference between UTC and the server is not full hour. e.g. +5:30 UTC. Is there any solution for that? Cheers, Ruwan On Mon,

[Architecture] [Analytics] Using UTC across all temporal analytics functions

Hi, In analytics use cases we use a couple of extensions to extract attributes (year, month, day, hour, etc.) from the event timestamp. In product anaytics implementations, we mostly use time:extract() Siddhi extension [1] in real time scenarios and DateTimeUDF in batch scenarios [2]. However,
