local_time_to_utc

Convert local time to UTC

This function converts local time to UTC via Java methods. It is therefore portable to Matlab on any platform. It can take as argument either a vector of datenums or a vector of datevecs (ie, local_time_to_utc(now) or local_time_to_utc([2008 01 01 00 00 00])). It formats the returned time as a Matlab date/time string with a post-pended 'Z' to indicate UTC.
