Elapsed times must take one of the forms:-

d:h:m:s
h:m:s
m:s
s

d = days, h = hours, m = minutes, s = seconds. Only integer values are allowed. There is no limit on values; for example minutes and seconds can have values greater then 60. Spaces are ignored. Alternative separators are:-

– / . ;

Do not mix separators in an elapsed time. For example the following elapsed times all equate to 1 hour and 1 minute and 1 second:-

0:1:1:1
1:1:1
1.0.61
01:01:01
61 / 1
61:01
60:61
0:3661
0:0:3661
0 – 0 – 0 – 3661
3661

Each component of the time can optionally contain alphabetic characters. Some users like to use them to improve readability. For example:-

1h : 1m : 1sec
hr 1 / min 1 / sec 1

Note that the numeric form is extended for use in the sailno wizard as described here.
