#
# Registers xlat to convert between time formats.
#
# xlat input string is an attribute name. If this attribute is of date
# or integer type, the date xlat will convert it to a time string in
# the format of the format config item.
#
# If the attribute is a string type, date will attempt to parse it in
# the format specified by the format config item, and will expand
# to a Unix timestamp.
#
date {
format = "%b %e %Y %H:%M:%S %Z"
# Use UTC instead of local time.
#
# default = no
# utc = yes
}
#
# The WISPr-Session-Terminate-Time attribute is of type "string",
# and not "date". Use this expansion to create an attribute
# that holds an actual date:
#
# Tmp-Date-0 := "%{wispr2date:&reply:WISPr-Session-Terminate-Time}"
#
date wispr2date {
format = "%Y-%m-%dT%H:%M:%S"
# Use UTC instead of local time.
#
# default = no
# utc = yes
}
#
# The date module also provides the %{time_since:} xlat, which
# makes it possible to both:
# - get the time since the epoch in seconds, milliseconds or
# microseconds; and
# - calculate the time elapsed since a given time.
#
# Syntax is: %{time_since:BASE[ (number|&attribute)]}
# where "BASE" is "s", "ms" or "us".
#
# Examples:
# %{time_since:s}
# - time in seconds since the epoch, same as %c
#
# %{time_since:s 1695753388}
# - time in seconds since Tue 26 Sep 19:36:28 BST 2023
# (which is 1695753388 in UNIX time)
#
# %{time_since:s &Tmp-Integer-0}
# - Time since the number of seconds in Tmp-Integer-0
#
# %{time_since:ms}
# - Milliseconds since the epoch
#
# %{time_since:us}
# - Microseconds since the epoch
#
# The provided attribute should be an Integer (or Integer64 for
# ms or us bases). However, other attributes will be converted if
# possible, with a warning given. The only one that might make
# sense is a Date attribute (which will be scaled appropriately
# according to the base, as Date is always in seconds).
#
# Primary usage would be for taking latenct measurements, for
# example to calculate the number of microseconds an LDAP call
# took:
#
# update request {
# &Tmp-Integer64-0 := %{time_since:us}"
# }
# ldap
# update request {
# &Tmp-Integer64-1 := %{time_since:us &Tmp-Integer64-0}"
# }
