Here's an example that does what you want:

In [32]: from datetime import datetime as dt

In [33]: dr = p.DateRange(dt(2009,1,1),dt(2010,12,31), offset=p.datetools.Hour())

In [34]: hr = dr.map(lambda x: x.hour)

In [35]: dt = p.DataFrame(rand(len(dr),2), dr)

In [36]: dt 

Out[36]: 

DateRange: 17497 entries, 2009-01-01 00:00:00 to 2010-12-31 00:00:00
offset: <1 Hour>
Data columns:
0    17497  non-null values
1    17497  non-null values
dtypes: float64(2)

In [37]: dt[(hr >= 10) & (hr <=16)]

Out[37]: 

Index: 5103 entries, 2009-01-01 10:00:00 to 2010-12-30 16:00:00
Data columns:
0    5103  non-null values
1    5103  non-null values
dtypes: float64(2)
