while the finish time and start time format
allow hhmmss and mmss, elapsed does not because a number is
interpreted as seconds (not relevant for start/finish times).
this is tripping people up. the interpretation as seconds is
needed for timers. i could assume hhmmss if it’s 6 digits
(unlikely to be elapsed) but not 4 digits - so if i did something
it would need to be an option somewhere, or, change it round and
force seconds to have a format which is possibly the better
default because it less likely to be used…?
i.e. propose
"2345" = 23min 45 sec
"012345" = 1 hr 23 min 45 sec
"12345" = 1 hr 23 min 45 sec
"2345s" = 2345 seconds
"012345s" = 12345 seconds
"12345s" = 12345 seconds
An upgrade could convert existing elapsed times in files.
