saving a waveform with negative times via sxs.rpdmb.save and then loading it yields a waveform with the negative times removed

[keefemitman]

h = sxs.load("SXS:BBH:0305).h
h_prime = h.copy()
h_prime.t -= 1000
sxs.rpdmb.save(h_prime, "test")
h_prime = sxs.load("test")
h_prime.t.size == h.t.size # this returns False

Yeah, this is because we decided to automatically drop times before zero by default. (In fact, I thought the suggestion came from you...) If you want to keep them around, you need to pass the kwarg drop_times_before="begin".

hmm ok; this makes sense for loading waveforms from the catalog, but it seems a little counter intuitive for loading waveforms from local files, since for most analyses (e.g., surrogates) we change the waveform data to make t=0 be the time of peak luminosity flux. Can we change the default depending on where the data is being loaded from?
