* PRTime --
*
* NSPR represents basic time as 64-bit signed integers relative
* to midnight (00:00:00), January 1, 1970 Greenwich Mean Time (GMT).
* (GMT is also known as Coordinated Universal Time, UTC.)
* The units of time are in microseconds. Negative times are allowed
* to represent times prior to the January 1970 epoch. Such values are
* intended to be exported to other systems or converted to human
* readable form.
*
* Notes on porting: PRTime corresponds to time_t in ANSI C. NSPR 1.0
* simply uses PRInt64.

* Time broken down into human-readable components such as year, month,
* day, hour, minute, second, and microsecond. Time zone and daylight
* saving time corrections may be applied. If they are applied, the
* offsets from the GMT must be saved in the 'tm_params' field so that
* all the information is available to reconstruct GMT.
*
* Notes on porting: PRExplodedTime corrresponds to struct tm in
* ANSI C, with the following differences:
* - an additional field tm_usec;
* - replacing tm_isdst by tm_params;
* - the month field is spelled tm_month, not tm_mon;
* - we use absolute year, AD, not the year since 1900.
* The corresponding type in NSPR 1.0 is called PRTime. Below is
* a table of date/time type correspondence in the three APIs:

* PRTimeParamFn --
*
* A function of PRTimeParamFn type returns the time zone and
* daylight saving time corrections for some geographic location,
* given the current time in GMT. The input argument gmt should
* point to a PRExplodedTime that is in GMT, i.e., whose
* tm_params contains all 0's.
*
* For any time zone other than GMT, the computation is intended to
* consist of two steps:
* - Figure out the time zone correction, tp_gmt_offset. This number
* usually depends on the geographic location only. But it may
* also depend on the current time. For example, all of China
* is one time zone right now. But this situation may change
* in the future.
* - Figure out the daylight saving time correction, tp_dst_offset.
* This number depends on both the geographic location and the
* current time. Most of the DST rules are expressed in local
* current time. If so, one should apply the time zone correction
* to GMT before applying the DST rules.
