4 GNUmed date/time handling.
5
6 This modules provides access to date/time handling
7 and offers an fuzzy timestamp implementation
8
9 It utilizes
10
11 - Python time
12 - Python datetime
13 - mxDateTime
14
15 Note that if you want locale-aware formatting you need to call
16
17 locale.setlocale(locale.LC_ALL, '')
18
19 somewhere before importing this script.
20
21 Note regarding UTC offsets
22 --------------------------
23
24 Looking from Greenwich:
25 WEST (IOW "behind"): negative values
26 EAST (IOW "ahead"): positive values
27
28 This is in compliance with what datetime.tzinfo.utcoffset()
29 does but NOT what time.altzone/time.timezone do !
30
31 This module also implements a class which allows the
32 programmer to define the degree of fuzziness, uncertainty
33 or imprecision of the timestamp contained within.
34
35 This is useful in fields such as medicine where only partial
36 timestamps may be known for certain events.
