In TS4 the delayed data from QC is timestamped correctly even though it is
received in bursts of 10 minutes at a time. The TS4 server seems to store
these fine. But in TS2K, I am told that although the Data Manager (which we
emulate) timestamps properly that Global Server uses the machine time when
it stores the tick data. I don't have TS2K myself nor other feeds, so I'm
not personnaly able to verify that. Bottom line is that we believe that we
timestamp properly (as TS4 shows to be true) but the TS2K GS apparently
ignores it.

Subject: Re: Anyone doing DynaStore/TS2k/QFeed real-time?
Hi Ron,
I have a question about Dynastore/TS4 and delayed data.
TS4 will plot delayed data from BMI or Signal but it's not very good
because (i think) it doesn't get the timestamp for each tick from the
data feed and just subtracts a generic 10 minutes or whatever from the
time the tick is received. So, charts created from delayed data don't
look the same as those created from realtime data.
Qcom has much better delayed data for most exchanges. Each tick has an
accurate timestamp but it arrives 10 minutes or whatever late. Does
Dynastore use the feed timestamp when it saves ticks to the TS server?
That would let you plot accurate historical charts for exchanges you
don't subscribe to.
