\subsection{Table of Dates and Times of Missing Data}

The following table shows the dates when there are gaps in Yohkoh data of more
than 12 hours.

\subsection{Dates that SXT CCD was Baked Out}

The following table shows the dates that the SXT CCD thermo electric
cooler (TEC) was turned off, and the TEC heater was turned on.  The
routine PR\_DATES\_WARM can generate this list at any time for sites
which have the SSL database.

\subsection{Time Conversions for Different Time Zones}

\index{time zones}\index{zones, time}

Fig.~\ref{demo_time_line} shows the offset in time zones for a few of
the time zones.  Find the zone you are in, and move directly up to the
time zone you want to know the time for.  The horizontal lines are the
approximate daylight hours for that local zone.
