Updated p5-Date-Manip to 6.58.

VERSION 6.58 2017-03-01 ^

Better support for $mode in DateCalc.

    DateCalc (in DM6) did not support all values for $mode. Now it does.

Bug fixes

    Parsing a date like 01/02/2016 and calling printf with %e gave '02' instead \ 
of ' 2'. RT 119787.

    Fixed a problem where the tzdata method of determining the timezone was \ 
producing an error which wasn't correct. Reported on GitHub by John.
