No, no reason.
I think it should present it as seconds if the number is <60 seconds,
as Minutes and Seconds if it is less than 1 hour,
etc.
This change would enhance useability a lot.

For relative 64bit timestamps I think we need to overload the BASE_xxx field
so that we can describe
BASE_USTIME (come up with better name):
1 a guint32 for secs
2 a guint32 for usecs
BASE_NSTIME
ditto as above but takes the second 32bit field as nsecs.
BASE_NDR
for a 64 bit value holding the 64bit value that represents the number of
ticks used for DCERPC (==windows)
ticks. I think it is something like number of x ns . This is a true
64 bit field and not 2 32 bit fields as above is.
and there are other types of 64 bit timestamps/deltas as well.
BASE_TIMET
which would be a single 32bit integer
Why not generalize it a bit more and also support even weirder ones such as
All the older types of timestamps/deltas used by DOS/Windows(old dialects)
like the weird one where timedeltas are specified in units of 2 seconds
etc...
