DNS zone import needs to deal with time abbreviations
When importing a DNS zone file (bind9 format), the import tool doesn't recognize abbreviations for times.
For example:
@ IN SOA ns1.compar.com. noc.compar.com. ( 2011100803 ;serial 3H ;refresh 1H ;retry 1W ;expire 1H ;minimum TTL (negative caching) )
In this case, 3H is interpreted as '3' (seconds), and 1H and 1H are interpreted as '1' (seconds).
The import tool needs to properly handle the following abbreviations m = minutes (60x multiplier) h = hours (3600x multiplier) d = days (86400x multiplier) w = weeks (604800x multiplier)
