Converts the local "time" input parameter into Coordinated Universal Time, or GMT/Zulu time. (The function takes the timezone component, e.g. +5:00, into account).
E.g. Instance document datetime:
departuredatetime="2001-12-17T09:30:02+05:00"
Result:
departuredatetime="2001-12-17T04:30:02"
Please note:
If the source dateTime is in the form departuredatetime="2001-12-17T09:30:02Z" then no conversion will take place because the trailing "Z" defines this time to be Zulu time, i.e. UTC. The result will be departuredatetime="2001-12-17T09:30:02".
