Below is a summary of stations for which the IGS Rapid
clocks so for this week have about 276 epochs per day.
A full set of 24 hr data should yield 288 epochs.  If
one hour is missing there will be 276 epochs.  (Some
of the stations named below for only one day may
represent merely isolated data losses.)

Evidently quite a few stations are losing an hour each
day.  This can happen in various ways:

* by station operators if data are not reported quickly
enough
* at Operational Data Centers if hourly files are
concatenated incompletely or not quickly enough
* at Analysis Centers that start their processing before
complete daily files are posted

This is an issue I've reported several times before but
it seems to be getting worse, not better.  Again, I ask
that all IGS components try to avoid the loss of full
hours of data or product results.  This is especially
difficult for the IGS Rapid clocks.
