# DateTime转换为字符串
(get-date).ToString("yyyy-MM-dd HH:mm:ss K")	# 2021-09-04 10:12:46 +08:00
Get-Date -Format "dddd MM/dd/yyyy HH:mm K"		# 2021-09-04 10:12:46 +08:00
# 字符串转换为DateTime
$datetime = [datetime]"2021-09-04 10:12:46 +08:00"
$datetime = [datetime]"2021-09-04 10:12:46"

Python

from datetime import datetime

 # 2021-09-04 10:12:46.12523
datetime.now().strftime("%Y-%m-%d %H:%M:%S.%f")

# datetime.datetime(2021, 9, 4, 10, 12, 46, 125230, tzinfo=datetime.timezone(datetime.timedelta(seconds=28800)))
datetime.strptime("2021-09-04 10:12:46.12523 +08:00", "%Y-%m-%d %H:%M:%S.%f %z")

# time.struct_time to datetime
datetime(*(time.strptime("2021-09-04 10:12:46.12523 +08:00", "%Y-%m-%d %H:%M:%S.%f %z")[0:6]))
