secs2ms(): Changes to digs[5] and digs sizeof sizeof

[Sackzement]

First commit changes this:

long val;
secs2ms(&val, "1.23456");   // val = 1234 // ok
secs2ms(&val, "1.234567");  // val = 1023 // should be 1234
secs2ms(&val, "1.2345678"); // val = 1234 // ok

Second commit would only be an issue if at some point sizeof(size_t) becomes larger than sizeof(digs) / sizeof(digs[0]).

Nice catch!
