Hello!
I notice I can convert strings containing hour, minute or second specifications
to a 'difftime':
> as.difftime("12 h", "%H")
Time difference of 12 hours

Time difference of 12 mins

Time difference of 12 secs

Dear Sirs,
while

[1] 2
attr(,"match.length")
[1] 2
attr(,"useBytes")
[1] TRUE
yields the correct match, an incremented upper bound in

[1] -1
attr(,"match.length")
[1] -1
attr(,"useBytes")
[1] TRUE
incorrectly yields no match.
