is there a way to say that '13Min' is > '59S' and <'2H' using the frequency notation in pandas?
In [4]: from pandas.tseries.frequencies import to_offset
In [5]: to_offset('59s') < to_offset('1T')
Out[5]: True
In [6]: to_offset('13T') > to_offset('59s')
Out[6]: True
In [7]: to_offset('13T') < to_offset('59s')
Out[7]: False
In [8]: to_offset('13T') > to_offset('2H')
Out[8]: False
In [10]: to_offset('13T') < to_offset('2H')
Out[10]: True
