You
can calculate the difference on your own as follows:
Set
V[hms] &V[today_hms]
Set V[sec] &V[hms](1,2) * 60
Set V[sec] &V[sec] + &V[hms](3,4)
Set V[sec] &V[sec] * 60
Set V[sec] &V[sec] + &V[hms](5,6)
if
V[sec_prev]
Set V[diff] &V[sec]  &V[sec_prev]
Message "&V[diff] seconds" statusline
endif
Set
V[sec_prev] &V[sec]
Return
Note: if the date
has just changed, the resulting "midnight"
case leads to a negative time difference that you may handle separately if
necessary.
