[PATCH] parse-datetime: use labs for long int

[Ruediger Meier]

From: Ruediger Meier <address@hidden>

clang warns about this:

lib/parse-date.y:909:16: warning: absolute value function 'abs' given an
      argument of type 'long' but has parameter of type 'int' which may cause
      truncation of value [-Wabsolute-value]
