heres to lost sleep
& all dreams postponed

but it is also wonderful to be roused into seeing that time zones in the
usa at least have always been rather flakey things at best
constantly shifting about in response to a great variety of local needs
rather than strictly regional ones alone
while answering also to many different ideas of daylight savings
of metro area limits
etc
hence the common expressions fast time & slow time around all the margins

& also to be reminded that attention to time everywhere is generally
focussed on a presumed lack of it
which does not in fact exist
