示例1: getClosestDate
# 需要导入模块: from DateTime import DateTime [as 别名]
# 或者: from DateTime.DateTime import _tz [as 别名]
def getClosestDate(date=None, target_date=None,
precision='month', before=1, strict=1):
"""
Return the closest date from target_date, at the given precision.
If date is set, the search is made by making steps of 'precision' duration.
If target_date is None, it is replaced by current time.
Precision can be year, month or day
If before is set to 1, return the closest date before target_date,
unless the closest date after target_date
Example :
date=None, target_date=DateTime('2004/03/12'), precision='month', before=1
-> return DateTime('2004/03/01')
date=DateTime('2002/12/14'), target_date=DateTime('2004/03/12'), precision='month', before=1
-> return DateTime('2004/02/14')
"""
