The <time> element represents the local time for an XMPP agent.
|
|
The time is expressed in UTC to make synchronization easier

between entities, but the offset for the local timezone is also

|
included.

|
|
|
Example <time> stanzas:
|
|
<iq type="result">
|

<time xmlns="urn:xmpp:time">

<utc>2011-07-03T11:37:12.234569</utc>

Stanza Interface:
|
|
time -- The local time for the entity (updates utc and tzo).
|
|
utc -- The UTC equivalent to local time.
|
|
tzo -- The local timezone offset from UTC.
|
|
|
|
Methods:
|
|
get_time -- Return local time datetime object.
|
|
set_time -- Set UTC and TZO fields.
|
|
del_time -- Remove both UTC and TZO fields.
|
|
get_utc -- Return datetime object of UTC time.
|
|
set_utc -- Set the UTC time.
|
|
get_tzo -- Return tzinfo object.

set_tzo -- Set the local timezone offset.
